General Description
The HMC239AS8 & HMC239AS8E 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”.
