GaAs IC SPDT Switch
Non-Reflective DC–2.5 GHz
Features
■ Low DC Power Consumption
■ High Isolation (40 dB @ 0.9 GHz)
■ Non-Reflective
Description
The AS338-12 is a low cost IC FET SPDT non-reflective
switch in a plastic SOIC-8 package for commercial
applications. The switch operates with -5, 0 V or 0, +5 V
when “floated” as shown on the following page. This
general purpose SPDT switch is used in various tele-
communications applications.
