GaAs MMIC POSITIVE CONTROL

TRANSFER SWITCH, DC* - 8 GHz

v07.0805

General Description

Features

Functional Diagram

The HMC427LP3 & HMC427LP3E are low loss

broadband

positive

control

transfer

switches

in

leadless surface mount packages. Covering DC to 8

GHz, this switch offers high isolation and low insertion

loss. The switch operates using a positive control

voltage of 0/+5V and requires a fixed bias of +5V @

< 20 μA.

High Isolation: 40 ~ 45 dB thru 6 GHz

Low Insertion Loss: 1.2 dB@ 6 GHz

Non-Reflective Design

3 x 3 mm SMT Package

Typical Applications

The HMC427LP3 / HMC427LP3E is ideal for:

• Test Instrumentation

• Fiber Optics & Broadband Telecom

• Basestation Infrastructure

• Microwave Radio & VSAT

• Military Radios, Radar, & ECM

* Blocking capacitors are required at ports RF1, 2, 3, &

4. Their value will determine the lowest transmission fre-

quency.
