_________________General Description
The MAX2620 combines a low-noise oscillator with two
output buffers in a low-cost, plastic surface-mount,
ultra-small µMAX package. This device integrates func-
tions typically achieved with discrete components. The
oscillator exhibits low-phase noise when properly
mated with an external varactor-tuned resonant tank
circuit. Two buffered outputs are provided for driving
mixers or prescalers. The buffers provide load isolation
to the oscillator and prevent frequency pulling due to
load-impedance changes. Power consumption is typi-
cally just 27mW in operating mode (VCC = 3.0V), and
drops to less than 0.3µW in standby mode. The MAX2620
operates from a single +2.7V to +5.25V supply.

_______________Detailed Description
Oscillator
The oscillator is a common-collector, negative-
resistance type that uses the IC’s internal parasitic ele-
ments to create a negative resistance at the base-
emitter port. The transistor oscillator has been opti-
mized for low-noise operation. Base and emitter leads
are provided as external connections for a feedback
capacitor and resonator. A resonant circuit, tuned to
the appropriate frequency and connected to the base
lead, will cause oscillation. Varactor diodes may be
used in the resonant circuit to create a voltage-con-
trolled oscillator (VCO). The oscillator is internally
biased to an optimal operating point, and the base and
emitter leads need to be capacitively coupled due to
the bias voltages present.
Output Buffers
The output buffers (OUT and OUT) are an open-
collector, differential-pair configuration and provide
load isolation to the oscillator. The outputs can be used
differentially to drive an integrated circuit mixer.
Alternatively, isolation is provided between the buffer
outputs when one output drives a mixer (either upcon-
version or downconversion) and the other output drives
a prescaler. The isolation in this configuration prevents
prescaler noise from corrupting the oscillator signal’s
spectral purity.
A logic-controlled SHDN pin turns off all bias to the IC
when pulled low.
__________Applications Information
Design Principles
At the frequency of interest, the MAX2620 portion of
Figure 2 shows the one-port circuit model for the TANK
pin (test port in Figure 1).
For the circuit to oscillate at a desired frequency, the res-
onant tank circuit connected to TANK must present an
impedance that is a complement to the network
(Figure 2). This resonant tank circuit must have a positive
real component that is a maximum of one-half the magni-
tude of the negative real part of the oscillator device, as
well as a reactive component that is opposite in sign to
the reactive component of the oscillator device.

Keeping the resonant tank circuit’s real component less
than one-half the magnitude of the negative real com-
ponent ensures that oscillations will start. After start-up,
the oscillator’s negative resistance decreases, primarily
due to gain compression, and reaches equilibrium with
the real component (the circuit losses) in the resonant
tank circuit. Making the resonant tank circuit reactance
tunable (e.g., through use of a varactor diode) allows
for tuneability of the oscillation frequency, as long as
the oscillator exhibits negative resistance over the
desired tuning range. See Figures 3 and 4.
The negative resistance of the MAX2620 TANK pin can
be optimized at the desired oscillator frequency by
proper selection of feedback capacitors C3 and C4.
For example, the one-port characteristics of the device
are given as a plot of 1/S11 in the Typical Operating
Characteristics. 1/S11 is used because it maps inside
the unit circle Smith chart when the device exhibits
negative resistance (reflection gain).

Sample Calculation
According to the electrical model shown in Figure 5, the
resonance frequency can be calculated as:
[Equation 1]
Rn, the negative real impedance, is set by C3 and C4
and is approximately:
[Equation 2]
where gm= 18mS.
Using the circuit model of Figure 5, the following exam-
ple describes the design of an oscillator centered at
900MHz.
Choose: L1 = 5nH ±10%
Q = 140
Calculate: Rp= Q ×2π×f ×L1
Using Equation 1, solve for varactor capacitance (CD1).
CD1 is the capacitance of the varactor when the volt-
age applied to the varactor is approximately at half-
supply (the center of the varactor’s capacitance range).
Assume the following values:
CSTRAY = 2.7pF, C17 = 1.5pF, C6 = 1.5pF, C5 = 1.5pF,
C03 = 2.4pF, C04 = 2.4pF, C3 = 2.7pF, and C4 = 1pF
The value of CSTRAY is based on approximate perfor-
mance of the MAX2620 EV kit. Values of C3 and C4 are
chosen to minimize Rn(Equation 2) while not loading
the resonant circuit with excessive capacitance. C03
and C04 are parasitic capacitors.
The varactor’s capacitance range should allow for the
desired tuning range. Across the tuning frequency
range, ensure that Rs< 1/2 Rn.
The MAX2620’s oscillator is optimized for low-phase-
noise operation. Achieving lowest phase-noise charac-
teristics requires the use of high-Q (quality factor)
components such as ceramic transmission-line type

resonators or high-Q inductors. Also, keep C5 and C17
(see the Typical Operating Circuit) as small a value as
possible while still maintaining desired frequency and
tuning range to maximize loaded Q.
There are many good references on the topic of oscilla-
tor design. An excellent reference is “The Oscillator
as a Reflection Amplifier, an Intuitive Approach to
Oscillator Design,” by John W. Boyles, Microwave
Journal, June 1986, pp. 83–98.
Output Matching Configuration
Both of the MAX2620’s outputs (OUT and OUT) are
open collectors. They need to be pulled up to the sup-
ply by external components. An easy approach to this
pull-up is a resistor. A 50resistor value would inher-
ently match the output to a 50system. The Typical
Operating Circuit shows OUT configured this way.
Alternatively, a choke pullup (Figure 1), yields greater
output power (approximately -8dBm at 900MHz).
When maximum power is required, use an inductor as
the supply pull-up, and match the inductor’s output
impedance to the desired system impedance. Table 1
in the Typical Operating Characteristics shows recom-
mended load impedance presented to OUT and OUT
for maximum power transfer. Using this data and stan-
dard matching-network synthesis techniques, a match-
ing network can be constructed that will optimize power
output into most load impedances. The value of the
inductor used for pullup should be used in the synthe-
sis of the matching network.
