HMC342

GaAs MMIC LOW NOISE

AMPLIFIER, 13 - 25 GHz

v01.0907

General Description

Features

Functional Diagram

The HMC342 chip is a GaAs MMIC

Low Noise

Amplifier (LNA) which covers the frequency range

of 13 to 25 GHz. The chip can easily be integrated

into Multi-Chip Modules (MCMs) due to its small

(2.14 mm

process offering 20 dB gain from a single bias

supply of +3V @ 41mA with a noise figure of 3.5 dB.

All data is with the chip in a 50 ohm test fixture con-

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

minimal length 0.31 mm (<12 mils).

Noise Figure : 3.5 dB

Gain: 20 dB

Single Supply : +3V @ 41mA

Small Size: 1.06 x 2.02 mm

Typical Applications

The HMC342 is ideal for:

• Microwave Point-to-Point Radios

• Millimeterwave Point-to-Point Radios

• VSAT & SATCOM
