HMC232

GaAs MMIC SPDT NON-REFLECTIVE

SWITCH, DC - 15 GHz

v03.1203

General Description

Features

Functional Diagram

The HMC232 is a broadband non-reflective GaAs

MESFET SPDT MMIC chip. Covering DC to 15 GHz,

the switch features over 55 dB isolation at lower

frequencies and over 45 dB at higher frequencies

due to the implementation of on-chip via hole

structures. The switch operates using two negative

control voltage logic lines (A&B) of -5/0V and requires

no Vee. Alternate A & B control pads are provided to

ease MIC implementation. All data shown is tested

with the chip in a 50 Ohm test fixture connected

via 0.025 mm (1 mil) diameter wire bonds of 0.5 mm

(20 mils) length. This product is a form, fit & functional

replacement for the HMC132.

High Isolation: >50 dB @ 10 GHz

Low Insertion Loss: 1.4 dB @ 6 GHz

Non-Reflective Design

Die Size: 2.05 x 1.04 x 0.1 mm

Direct Replacement for HMC132

Typical Applications

Broadband switch for DC - 15 GHz applications:

• Fiber Optics

• Microwave Radio

• Military & Space

• Test Equipment

• VSAT
