GaAs MMIC SPDT NON-REFLECTIVE

SWITCH, DC - 14 GHz

v06.0805

General Description

Features

Functional Diagram

The HMC347LP3 & HMC347LP3E are broadband

high isolation non-reflective GaAs MESFET SPDT

switches in low cost leadless QFN surface mount

plastic packages. Covering DC to 14 GHz, the switch

offers high isolation and low insertion loss. The switch

features >50 dB isolation up to 3 GHz and >40 dB

isolation up to 13 GHz. The switch operates using

complementary negative control voltage logic lines of

-5/0V and requires no bias supply. This SPDT is an

excellent alternative to the HMC132C8 SPDT.

High Isolation: >50 dB up to 3 GHz

>45 dB up to 10 GHz

Low Insertion Loss: 1.6 dB @ 10 GHz

Non-Reflective Design

3x3 mm QFN SMT Package

Typical Applications

The HMC347LP3 / HMC347LP3E is ideal for:

• Basestation Infrastructure

• Fiber Optics & Broadband Telecom

• Microwave Radio & VSAT

• Military Radios, Radar, & ECM

• Test Instrumentation
