GaAs MMIC SPDT SWITCH

NON-REFLECTIVE, DC - 8 GHz

v04.0607

General Description

Features

Functional Diagram

Broadband Performance: DC - 8 GHz

Very High Isolation: 45 dB @ 6 GHz

Non-Reflective Design

Typical Applications

The HMC270MS8G / HMC270MS8GE is ideal for

DC - 8.0 GHz applications:

• CATV

• MMDS & WirelessLAN

• Wireless Local Loop

The HMC270MS8G & HMC270MS8GE are broad-

band non-reflective GaAs SPDT switches in 8

lead MSOP grounded base surface mount plastic

packages. Covering DC to 8 GHz, the switch offers

excellent isolation from 70 to 35 dB. The negative

control voltage of -5 volts allows operation down

to DC. If positive control is required along with high

isolation, see the DC to 3.5 GHz HMC284MS8G non-

reflective SPDT.
