MOTOROLA RF/IF DEVICE DATA
The MC13156 is a wideband FM IF subsystem targeted at high
performance data and analog applications. Excellent high frequency
performance is achieved at low cost using Motorola’s MOSAIC 1.5bipolar
process. The MC13156 has an onboard grounded collector VCO transistor
that may be used with a fundamental or overtone crystal in single channel
operation or with a PLL in multichannel operation. The mixer is useful to
500 MHz and may be used in a balanced–differential, or single–ended
configuration. The IF amplifier is split to accommodate two low cost
cascaded filters. RSSI output is derived by summing the output of both IF
sections. A precision data shaper has a hold function to preset the shaper for
fast recovery of new data.
Applications for the MC13156 include CT–2, wideband data links and
other radio systems utilizing GMSK, FSK or FM modulation.

MOTOROLA RF/IF DEVICE DATA
CIRCUIT DESCRIPTION
General
The MC13156 is a low power single conversion wideband
FM receiver incorporating a split IF. This device is designated
for use as the backend in digital FM systems such as CT–2
and wideband data links with data rates up to 500 kbaud. It
contains a mixer, oscillator, signal strength meter drive, IF
amplifier, limiting IF, quadrature detector and a data slicer
with a hold function (refer to Figure 8, Simplified Internal
Circuit Schematic).
Current Regulation
Temperature compensating voltage independent current
regulators are used throughout.
Mixer
The mixer is a double–balanced four quadrant multiplier
and is designed to work up to 500 MHz. It can be used in
differential or in single–ended mode by connecting the other
input to the positive supply rail.
Figure 4 shows the mixer gain and saturated output
response as a function of input signal drive. The circuit used
to measure this is shown in Figure 1. The linear gain of the
mixer is approximately 22 dB. Figure 9 shows the mixer gain
versus the IF output frequency with the local oscillator of
150 MHz at 100 mVrms LO drive level. The RF frequency is
swept. The sensitivity of the IF output of the mixer is shown in
Figure 10 for an RF input drive of 10 mV rms at 140 MHz and
IF at 10 MHz.
The single–ended parallel equivalent input impedance of
the mixer is Rp ~ 1.0 kΩ and Cp ~ 4.0 pF (see Table 1 for
details). The buffered output of the mixer is internally loaded
resulting in an output impedance of 330 Ω.
Local Oscillator
The on–chip transistor operates with crystal and LC
resonant elements up to 220 MHz. Series resonant, overtone
crystals are used to achieve excellent local oscillator stability .
3rd overtone crystals are used through about 65 to 70 MHz.
Operation from 70 MHz up to 180 MHz is feasible using the
on–chip transistor with a 5th or 7th overtone crystal. To
enhance operation using an overtone crystal, the internal
transistor ’s bias is increased by adding an external resistor
from Pin 23 to VEE. –10 dBm of local oscillator drive is
needed to adequately drive the mixer (Figure 10).
The oscillator configurations specified above, and two
others using an external transistor, are described in the
application section:
1) A 133 MHz oscillator multiplier using a 3rd overtone
1) crystal, and
2) A 307.8 to 309.3 MHz manually tuned, varactor controlled
2) local oscillator.
RSSI
The Received Signal Strength Indicator (RSSI) output is a
current proportional to the log of the received signal
amplitude. The RSSI current output is derived by summing
the currents from the IF and limiting amplifier stages. An
external resistor at Pin 20 sets the voltage range or swing of
the RSSI output voltage. Linearity of the RSSI is optimized by
using external ceramic or crystal bandpass filters which have
an insertion loss of 8.0 dB. The RSSI circuit is designed to
provide 70+ dB of dynamic range with temperature
compensation (see Figures 6 and 7 which show RSSI
responses of the IF and Limiter amplifiers). Variation in the
RSSI output current with supply voltage is small (see
Figure 11).
Carrier Detect
When the meter current flowing through the meter load
resistance reaches 1.2 Vdc above ground, the comparator
flips, causing the carrier detect output to go high. Hysteresis
can be accomplished by adding a very large resistor for
positive feedback between the output and the input of the
comparator.
IF Amplifier
The first IF amplifier section is composed of three
differential stages with the second and third stages
contributing to the RSSI. This section has internal dc
feedback and external input decoupling for improved
symmetry and stability . The total gain of the IF amplifier block
is approximately 39 dB at 10.7 MHz. Figure 5 shows the gain
and saturated output response of the IF amplifier over
temperature, while Figure 12 shows the IF amplifier gain as a
function of the IF frequency.
The fixed internal input impedance is 1.4 kΩ. It is designed
for applications where a 455 kHz ceramic filter is used and no
external output matching is necessary since the filter requires
a 1.4 kΩ source and load impedance.
For 10.7 MHz ceramic filter applications, an external
430 Ω resistor must be added in parallel to provide the
equivalent load impedance of 330 Ω that is required by the
filter; however , no external matching is necessary at the input
since the mixer output matches the 330 Ω source impedance
of the filter. For 455 kHz applications, an external 1.1 kΩ
resistor must be added in series with the mixer output to
obtain the required matching impedance of 1.4 kΩ of the filter
input resistance. Overall RSSI linearity is dependent on
having total midband attenuation of 12 dB (6.0 dB insertion
loss plus 6.0 dB impedance matching loss) for the filter. The
output of the IF amplifier is buffered and the impedance is
290 Ω.
Limiter
The limiter section is similar to the IF amplifier section
except that four stages are used with the last three
contributing to the RSSI. The fixed internal input impedance
is 1.4 kΩ. The total gain of the limiting amplifier section is
approximately 55 dB. This IF limiting amplifier section
internally drives the quadrature detector section.

MOTOROLA RF/IF DEVICE DATA
Quadrature Detector
The quadrature detector is a doubly balanced four
quadrant multiplier with an internal 5.0 pF quadrature
capacitor to couple the IF signal to the external parallel RLC
resonant circuit that provides the 90 degree phase shift and
drives the quadrature detector. A single pin (Pin 13) provides
for the external LC parallel resonant network and the internal
connection to the quadrature detector.
The bandwidth of the detector allows for recovery of
relatively high data rate modulation. The recovered signal is
converted from differential to single ended through a
push–pull NPN/PNP output stage. Variation in recovered
audio output voltage with supply voltage is very small (see
Figure 13). The output drive capability is approximately
±9.0 µA for a frequency deviation of ±75 kHz and 1.0 kHz
modulating frequency (see Application Circuit).
Data Slicer
The data slicer input (Pin 15) is self centering around 1.1 V
with clamping occurring at 1.1 ± 0.5 Vbe Vdc. It is designed to
square up the data signal. Figure 14 shows a detailed
schematic of the data slicer.
The Voltage Regulator
sets up 1.1 Vdc on the base of
Q12,
the
Differential Input Amplifier
.
There is a potential of
1.0 Vbe on the base–collector of transistor diode Q11 and
2.0 Vbe on the base–collector of Q10. This sets up a 1.5 Vbe
(~ 1.1 Vdc) on the node between the 36 kΩ resistors which is
connected to the base of Q12. The differential output of the
data slicer Q12 and Q13 is converted to a single–ended
output by the Driver Circuit. Additional circuitry, not shown in
Figure 14, tends to keep the data slicer input centered at
1.1 Vdc as input signal levels vary.
The Input Diode Clamp Circuit provides the clamping at
1.0 Vbe (0.75 Vdc) and 2.0 Vbe (1.45 Vdc). Transistor diodes
Q7 and Q8 are on, thus, providing a 2.0 Vbe potential at the
base of Q1. Also, the voltage regulator circuit provides a
potential of 2.0 Vbe on the base of Q3 and 1.0 Vbe on the
emitter of Q3 and Q2. When the data slicer input (Pin 15) is
pulled up, Q1 turns off; Q2 turns on, thereby clamping the
input at 2.0 Vbe. On the other hand, when Pin 15 is pulled
down, Q1 turns on; Q2 turns off, thereby clamping the input at
1.0 Vbe.
The recovered data signal from the quadrature detector is
ac coupled to the data slicer via an input coupling capacitor.
The size of this capacitor and the nature of the data signal
determine how faithfully the data slicer shapes up the
recovered signal. The time constant is short for large peak to
peak voltage swings or when there is a change in dc level at
the detector output. For small signal or for continuous bits of
the same polarity which drift close to the threshold voltage,
the time constant is longer. When centered there is no input
current allowed, which is to say, that the input looks high in
impedance.
Another unique feature of the data slicer is that it responds
to various logic levels applied to the Data Slicer Hold Control
pin (Pin 18). Figure 15 illustrates how the input and output
currents under “no hold” condition relate to the input voltage.
Figure 16 shows how the input current and input voltage
relate for both the “no hold” and “hold” condition.
The hold control (Pin18) does three separate tasks:
1) With Pin 18 at 1.0 Vbe or greater, the output is shut off
(sets high). Q19 turns on which shunts the base drive
from Q20, thereby turning the output off.
2) With Pin 18 at 2.0 Vbe or greater, internal clamping diodes
are open circuited and the comparator input is shut off and
effectively open circuited. This is accomplished by turning
off the current source to emitters of the input differential
amplifier, thus, the input differential amplifier is shut off.
3) When the input is shut off, it allows the input capacitor to
hold its charge during transmit to improve recovery at the
beginning of the next receive period. When it is turned on,
it allows for very fast charging of the input capacitor for
quick recovery of new tuning or data average. The above
features are very desirable in a TDD digital FM system.

APPLICATIONS INFORMATION
Component Selection
The evaluation PC board is designed to accommodate
specific components, while also being versatile enough to
use components from various manufacturers and coil types.
Figures NO TAG and NO TAG show the placement for the
components specified in the application circuit (Figure 17).
The applications circuit schematic specifies particular
components that were used to achieve the results shown in
the typical curves and tables but equivalent components
should give similar results.
Input Matching Networks/Components
The input matching circuit shown in the application circuit
schematic is passive high pass network which offers ef fective
image rejection when the local oscillator is below the RF input
frequency. Silver mica capacitors are used for their high Q
and tight tolerance. The PC board is not dedicated to any
particular input matching network topology; space is provided
for the designer to breadboard as desired.
Alternate matching networks using 4:1 surface mount
transformers or BALUNS provide satisfactory performance.
The 12 dB SINAD sensitivity using the above matching
networks is typically –100 dBm for fmod = 1.0 kHz and
fdev = ±75 kHz at fIN = 144.45 MHz and fOSC = 133.75 MHz
(see Figure 23).
It is desirable to use a SAW filter before the mixer to
provide additional selectivity and adjacent channel rejection
and improved sensitivity. The SAW filter should be designed
to interface with the mixer input impedance of approximately
1.0 kΩ. Table 1 displays the series equivalent single–ended
mixer input impedance.
Local Oscillators
VHF Applications – The local oscillator circuit shown in the
application schematic utilizes a third overtone crystal and an
RF transistor . Selecting a transistor having good phase noise
performance is important; a mandatory criteria is for the
device to have good linearity of beta over several decades of
collector current. In other words, if the low current beta is
suppressed, it will not offer good 1/f noise performance. A
third overtone series resonant crystal having at least 25 ppm
tolerance over the operating temperature is recommended.
The local oscillator is an impedance inversion third overtone
Colpitts network and harmonic generator. In this circuit a 560
to 1.0 kΩ resistor shunts the crystal to ensure that it operates
in its overtone mode; thus, a blocking capacitor is needed to
eliminate the dc path to ground. The resulting parallel LC
network should “free–run” near the crystal frequency if a
short to ground is placed across the crystal. To provide
sufficient output loading at the collector, a high Q variable
inductor is used that is tuned to self resonate at the 3rd
harmonic of the overtone crystal frequency.
The on–chip grounded collector transistor may be used for
HF and VHF local oscillator with higher order overtone
crystals. Figure 18 shows a 5th overtone oscillator at
93.3 MHz and Figure 19 shows a 7th overtone oscillator at
148.3 MHz. Both circuits use a Butler overtone oscillator
configuration. The amplifier is an emitter follower . The crystal
is driven from the emitter and is coupled to the high
impedance base through a capacitive tap network. Operation
at the desired overtone frequency is ensured by the parallel
resonant circuit formed by the variable inductor and the tap
capacitors and parasitic capacitances of the on–chip
transistor and PC board. The variable inductor specified in
the schematic could be replaced with a high tolerance, high Q
ceramic or air wound surface mount component if the other
components have good tolerances. A variable inductor
provides an adjustment for gain and frequency of the
resonant tank ensuring lock up and startup of the crystal
oscillator. The overtone crystal is chosen with ESR of
typically 80 Ω and 120 Ω maximum; if the resistive loss in the
crystal is too high, the performance of the oscillator may be
impacted by lower gain margins.

MOTOROLA RF/IF DEVICE DATA
A series LC network to ground (which is VCC) is comprised
of the inductance of the base lead of the on–chip transistor
and PC board traces and tap capacitors. Parasitic
oscillations often occur in the 200 to 800 MHz range. A small
resistor is placed in series with the base (Pin 24) to cancel the
negative resistance associated with this undesired mode of
oscillation. Since the base input impedance is so large a
small resistor in the range of 27 to 68 Ω has very little effect
on the desired Butler mode of oscillation.
The crystal parallel capacitance, Co, provides a feedback
path that is low enough in reactance at frequencies of 5th
overtone or higher to cause trouble. Co has little effect near
resonance because of the low impedance of the crystal
motional arm (Rm–Lm–Cm). As the tunable inductor which
forms the resonant tank with the tap capacitors is tuned off
the crystal resonant frequency, it may be difficult to tell if the
oscillation is under crystal control. Frequency jumps may
occur as the inductor is tuned. In order to eliminate this
behavior an inductor (Lo) is placed in parallel with the crystal.
Lo is chosen to resonant with the crystal parallel capacitance
(Co) at the desired operation frequency. The inductor
provides a feedback path at frequencies well below
resonance; however, the parallel tank network of the tap
capacitors and tunable inductor prevent oscillation at these
frequencies.
UHF Application
Figure 20 shows a 318.5 to 320 MHz receiver which drives
the mixer with an external varactor controlled (307.8 to
309.3 MHz) LC oscillator using an MPS901 (RF low power
transistor in a TO–92 plastic package; also MMBR901 is
available in a SOT–23 surface mount package). With the
50 kΩ 10 turn potentiometer this oscillator is tunable over a
range of approximately 1.5 MHz. The MMBV909L is a low
voltage varactor suitable for UHF applications; it is a dual
back–to–back varactor in a SOT–23 package. The input
matching network uses a 1:4 impedance matching
transformer (Recommended sources are Mini–Circuits and
Coilcraft).
Using the same IF ceramic filters and quadrature detector
circuit as specified in the applications circuit in Figure 17, the
12 dB SINAD performance is –95 dBm for a fmod = 1.0 kHz
sinusoidal waveform and fdev ±40 kHz.
This circuit is breadboarded using the evaluation PC board
shown in Figures NO TAG and NO TAG. The RF ground is
VCC and path lengths are minimized. High quality surface
mount components were used except where specified. The
absolute values of the components used will vary with layout
placement and component parasitics.
RSSI Response
Figure 24 shows the full RSSI response in the application
circuit. The 10.7 MHz, 110 kHz wide bandpass ceramic filters
(recommended sources are TOKO part # SK107M5–AO–10X
or Murata Erie SFE10.7MHY–A) provide the correct
bandpass insertion loss to linearize the curve between the
limiter and IF portions of RSSI. Figure 23 shows that limiting
occurs at an input of –100 dBm. As shown in Figure 24, the
RSSI output linear from –100 dBm to –30 dBm.
The RSSI rise and fall times for various RF input signal
levels and R20 values are measured at Pin 20 without 10 nF
filter capacitor. A 10 kHz square wave pulses the RF input
signal on and off. Figure 25 shows that the rise and fall times
are short enough to recover greater than 10 kHz ASK data;
with a wider IF bandpass filters data rates up to 50 kHz may
be achieved. The circuit used is the application circuit in
Figure 17 with no RSSI output filter capacitor.

45 MHz Narrowband Receiver
The above application examples utilize a 10.7 MHz IF. In
this section a narrowband receiver with a 455 kHz IF will be
described. Figure 21 shows a full schematic of a 45 MHz
receiver that uses a 3rd overtone crystal with the on–chip
oscillator transistor. The oscillator configuration is similar to
the one used in Figure 17; it is called an impedance inversion
Colpitts. A 44.545 MHz 3rd overtone, series resonant crystal
is used to achieve an IF frequency at 455 kHz. The ceramic
IF filters selected are Murata Erie part # SFG455A3. 1.2 kΩ
chip resistors are used in series with the filters to achieve the
terminating resistance of 1.4 kΩ to the filter. The IF
decoupling is very important; 0.1 µF chip capacitors are used
at Pins 6, 7, 11 and 12. The quadrature detector tank circuit
uses a 455 kHz quadrature tank from Toko.
The 12 dB SINAD performance is –109 dBm for a fmod =
1.0 kHz and a fdev = ±4.0 kHz. The RSSI dynamic range is
approximately 80 dB of linear range (see Figure 22).
Receiver Design Considerations
The curves of signal levels at various portions of the
application receiver with respect to RF input level are shown
in Figure 26. This information helps determine the network
topology and gain blocks required ahead of the MC13156 to
achieve the desired sensitivity and dynamic range of the
receiver system. In the application circuit the input third order
intercept (IP3) performance of the system is approximately
–25 dBm (see Figure 27).

BER TESTING AND PERFORMANCE
Description
The test setup shown in Figure 29 is configured so that the
function generator supplies a 100 kHz clock source to the bit
error rate tester. This device generates and receives a
repeating data pattern and drives a 5 pole baseband data
filter. The filter effectively reduces harmonic content of the
baseband data which is used to modulate the RF generator
which is running at 144.45 MHz. Following processing of the
signal by the receiver (MC13156), the recovered baseband
sinewave (data) is AC coupled to the data slicer. The data
slicer is essentially an auto–threshold comparator which
tracks the zero crossing of the incoming sinewave and
provides logic level data at its ouput. Data errors associated
with the recovered data are collected by the bit error rate
receiver and displayed.
Bit error rate versus RF signal input level and IF filter
bandwidth are shown in Figure 28. The bit error rate data was
taken under the following test conditions:
•Data rate = 100 kbps
•Filter cutoff frequency set to 39% of the data rate or 39 kHz.
•Filter type is a 5 pole equal–ripple with 0.5° phase error.
•VCC = 4.0 Vdc
•Frequency deviation = ±32 kHz.

Evaluation PC Board
The evaluation PCB is very versatile and is intended to be
used across the entire useful frequency range of this device.
The center section of the board provides an area for
attaching all SMT components to the circuit side and radial
leaded components to the component ground side (see
Figures NO TAG and NO TAG). Additionally, the peripheral
area surrounding the RF core provides pads to add
supporting and interface circuitry as a particular application
dictates.
