ADG936/ADG936-R
APPLICATIONS
The ADG936/ADG936-R 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. They can be used
in applications such as switchable filters, transmitters and
receivers for radar systems, and communication systems from
base stations to cell phones.

The ADG9xx family of wideband switches is designed to meet
the demands of devices transmitting at ISM band frequencies to
1 GHz and higher. The low insertion loss, high isolation
between ports, single pin control interface, no requirement for
dc blocking capacitors, and TTL interface compatibility make
them cost-effective and easy-to-integrate switching solutions for
many high frequency switching and low power applications,
because the parts can handle up to 16 dBm of power.
ABSORPTIVE VS. REFLECTIVE
The ADG936 is an absorptive (matched) switch with 50
terminated shunt legs; the ADG936-R is a reflective switch with
0 terminated shunts to ground. The ADG936 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 ADG936
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 ADG936-R reflective switch is suitable for applications in
which high off-port VSWR does not matter, and the switch has
some other desired performance features. 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.
FILTER SELECTION
The ADG936 and ADG936-R can be used to switch high
frequency signals between different filters, and to multiplex the
signal to the output. These dual SPDT switches are also ideal for
high speed signal routing and for switching high speed
differential signals.

Tx/Rx SWITCHING
The low insertion loss and high isolation between ports ensure
that the ADG936/ADG936-R are suitable transmit/receive
switches for all ISM band and Wireless LAN applications,
providing the required isolation between the transmit and
receive signals.

ANTENNA DIVERSITY SWITCH
The ADG936/ADG936-R are ideal for use as antenna diversity
switches, switching in different antennas to the tuner. The low
insertion loss, which ensures minimum signal loss and high
isolation between channels, makes these dual SPDT switches
suitable for switching applications in tuner modules and set-top
boxes.
