AS156-73
Description
The AS156-73 is an SPST FET IC switch. The switch
requires external DC blocking capacitors and one
bypass capacitor.Isolation is optimized at 0.9 GHz utilizing
100 pF bypass capacitor and optimized at 1.9 GHz utilizing
a 2.7 pF bypass capacitor.This switch requires a positive
supply and single positive control.The device is mounted
in the SOT-6 package for surface mounting in commercial
switching applications, specifically as an LNA bypass
switch.
