GENERAL DESCRIPTION
The ADG918/ADG919 are wideband switches using a CMOS
process to provide high isolation and low insertion loss to
1 GHz. The ADG918 is an absorptive (matched) switch having
50 Ω terminated shunt legs, whereas the ADG919 is a reflective
switch. These devices are designed such that the isolation is
high over the dc to 1 GHz frequency range. They have on-board
CMOS control logic, thus eliminating the need for external
controlling circuitry. The control inputs are both CMOS and
LVTTL compatible. The low power consumption of these
CMOS devices makes them ideally suited to wireless and
general-purpose high frequency switching applications.
PRODUCT HIGHLIGHTS
1. –43 dB off isolation @ 1 GHz.
2. 0.8 dB insertion loss @ 1 GHz.
3. Tiny 8-lead MSOP/LFCSP packages.

TERMINOLOGY
VDD
Most positive power supply potential.
IDD
Positive supply current.
GND
Ground (0 V) reference.
CTRL
Logic control input.
VINL
Maximum input voltage for Logic 0.
VINH
Minimum input voltage for Logic 1.
IINL (IINH)
Input current of the digital input.
CIN
Digital input capacitance.
tON
Delay between applying the digital control input and the output
switching on.
tOFF
Delay between applying the digital control input and the output
switching off.
tRISE
Rise time; time for the RF signal to rise from 10% to 90% of the
on level.
tFALL
Fall time; time for the RF signal to fall from 90% to 10% of the
on level.
Off Isolation
The attenuation between the input and output ports of the
switch when the switch control voltage is in the off condition.
Insertion Loss
The attenuation between the input and output ports of the
switch when the switch control voltage is in the on condition.
P–1 dB
1 dB compression point. The RF input power level at which the
switch insertion loss increases by 1 dB over its low level value. It
is a measure of how much power the on switch can handle
before the insertion loss increases by 1 dB.
IP3
Third order intermodulation intercept. This is a measure of the
power in false tones that occur when closely spaced tones are
passed through a switch, whereby the nonlinearity of the switch
causes these false tones to be generated.
Return Loss
The amount of reflected power relative to the incident power at
a port. Large return loss indicates good matching. By measuring
return loss, the VSWR (voltage standing wave ratio) can be
calculated from conversion charts. VSWR indicates the degree
of matching present at a switch RF port.
Video Feedthrough
Spurious signals present at the RF ports of the switch when the
control voltage is switched from high to low or low to high
without an RF signal present.

APPLICATIONS INFORMATION
The ADG918/ADG919 are ideal solutions for low power, high
frequency applications. The low insertion loss, high isolation
between ports, low distortion, and low current consumption of
these parts make them excellent solutions for many high
frequency switching applications. The most obvious application
is in a transmit/receive block, as shown in the wireless metering
block diagram in Figure 26.
Other applications include switching between high frequency
filters, an ASK generator, an FSK generator, and an antenna
diversity switch in many tuner modules.
ABSORPTIVE VS. REFLECTIVE SWITCH
The ADG918 is an absorptive (matched) switch with 50 Ω
terminated shunt legs, and the ADG919 is a reflective switch
with 0 Ω terminated shunts to ground. The ADG918 absorptive
switch has a good VSWR on each port, regardless of the switch
mode. An absorptive switch should be used when there is a need
for a good VSWR that is looking into the port but not passing
the through signal to the common port. The ADG918 is there-
fore ideal for applications that require minimum reflections
back to the RF source. It also ensures that the maximum power
is transferred to the load.
The ADG919 reflective switch is suitable for applications where
high off port VSWR does not matter and the switch has some
other desired performance feature. It can be used in many
applications, including high speed filter selection. In most cases,
an absorptive switch can be used instead of a reflective switch,
but not vice versa.
WIRELESS METERING
The ADG918 can be used in wireless metering applications. It
can be used in conjunction with the ADF7020 transceiver IC for
a utility metering transceiver application, providing the
required isolation between the transmit and receive signals.
The SPDT configuration isolates the high frequency receive
signal from the high frequency transmit.

TUNER MODULES
The ADG918 can be used in a tuner module to switch between
the cable TV input and the off-air antenna. This part is also
ideal for use as an antenna diversity switch, switching different
antenna to the tuner.

FILTER SELECTION
The ADG919 can be used as a 2:1 demultiplex to switch high
frequency signals between different filters and also to multiplex
the signal to the output.

ADG9xx EVALUATION BOARD
The ADG9xx evaluation board allows designers to evaluate the
high performance wideband switches with a minimum of effort.
In addition to the evaluation board, the user requires only a
power supply and a network analyzer. An application note is
available with the evaluation board and gives complete
information about operating the evaluation board.
The RFC port (see Figure 29) is connected through a 50 Ω
transmission line to the top left SMA connector J1. RF1 and
RF2 are connected through 50 Ω transmission lines to the top
two SMA connectors, J2 and J3 respectively. A through trans-
mission line connects J4 and J5 and is used to estimate the loss
of the PCB over the environmental conditions being evaluated.
The board is constructed of a 4-layer, FR4 material with a
dielectric constant of 4.3 and an overall thickness of 0.062
inches. Two ground layers with grounded planes provide
ground for the RF transmission lines. The transmission lines
were designed using a coplanar waveguide with ground plane
model using a trace width of 0.052 inches, a clearance to ground
plane of 0.030 inches, a dielectric thickness of 0.029 inches, and
a metal thickness of 0.014 inches.
