GaAs MMIC T/R SWITCH

5.0 - 6.0 GHz

v02.0805

General Description

Features

Functional Diagram

Low Cost 5-6 GHz Switch

Ultra Small Package: MSOP8

High Input P1dB: +33 dBm

Single Positive Supply: +3 to +8V

Typical Applications

The HMC224MS8 / HMC224MS8E is ideal for:

• UNII & HiperLAN

• PCMCIA WirelessLAN

The HMC224MS8 & HMC224MS8E are low-cost

SPDT switches in 8-lead MSOP packages for use in

transmit-receive applications. The device can control

signals from 5.0 to 6.0 GHz and is especially suited

for 5.2 GHz UNII and 5.8 GHz ISM applications with

only 1.2 dB loss. The design provides exceptional

power handling performance; input P1dB = +33 dBm

at 5 Volt bias. RF1 and RF2 are reflective shorts

when “Off”.

On-chip circuitry allows single positive

supply operation at very low DC current with control

inputs compatible with CMOS and most TTL logic

families. No DC blocking capacitors are required on

RF I/O ports.
