Functional Diagram
General Description
The HMC239S8 & HMC239S8E are low-cost GaAs
MMIC SPDT switches in 8-lead SOIC packages. The
switch can control signals from DC to 2.5 GHz. It is
especially suited for low or medium power applica-
tions which require extremely fast switching with
minimal insertion loss. The two control voltages
require a minimal amount of DC current which is opti-
mal for battery powered radio systems. RF1 and RF2
are reflective shorts when “Off”.
