Typical Applications

the hMc239AS8 / hMc239AS8e is ideal for:

• MMDS & WirelessLAN

• Basestation Infrastructure

• Portable Wireless

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”.
