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 a 100 pF bypass capac-
itor 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.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
