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, while 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

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

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.

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.

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 can be calculated from conversion charts. VSWR (voltage standing wave ratio) indicates
degree of matching present at a switch RF port.

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.

ADG918/ADG919

APPLICATIONS

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.

required isolation between the transmit and receive signals.
The SPDT configuration isolates the high frequency receive
signal from the high frequency transmit.

ANTENNA

ADG918

LNA

Other applications include switching between high frequency
filters, ASK generator, FSK generator, and antenna diversity
switch in many tuner modules.

ABSORPTIVE VS. REFLECTIVE

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
therefore 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

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.

To prove that these devices meet the user’s requirements, the
user only requires a power supply and a network analyzer along
with the evaluation board. An application note is available with
the evaluation board and gives complete information on
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
transmission line connects J4 and J5 and this transmission line
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, clearance to ground
plane of 0.030 inches, dielectric thickness of 0.029 inches, and a
metal thickness of 0.014 inches.
