ADG901/ADG902
APPLICATIONS
The ADG901/ADG902 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.
Applications include switching between high frequency filters,
ASK generators, and FSK generators.
ABSORPTIVE vs. REFLECTIVE SWITCHES
The ADG901 is an absorptive (matched) switch with
50 Ω terminated shunt legs and the ADG902 is a reflective
switch with 0 Ω terminated shunts to ground. The ADG901
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
ADG901 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 ADG902 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.
