HMC1024

v00.0312

GaAs pHEMT MMIC 1 WATT

POWER AMPLIFIER, 27.5 - 33.5 GHz

General Description

Features

Functional Diagram

The hmC1024 is a four stage GaAs phemT mmiC

1 watt power Amplifier which operates between 27.5

and 33.5 Ghz. The hmC1024 provides 24 dB of gain,

+31 dBm of saturated output power, and 29% pAe

from a +5 V power supply. The hmC1024 exhibits

excellent linearity and is optimized for high capacity

point to point and point to multi-point radio systems.

The amplifier configuration and high gain make it an

excellent candidate for last stage signal amplification

before the antenna. All data is taken with the chip in a

50 ohm test fixture connected via (2) 0.025 mm (1 mil)

diameter wire bonds of 0.31 mm (12 mil) length.

saturated output power: +31 dBm @ 29% pAe

high output ip3: +40 dBm

high Gain: 24 dB

DC supply: +5V @ 600 mA

no external matching required

Die size: 2.79 x 1.3 x 0.1 mm

Typical Applications

The hmC1024 is ideal for:

• Point-to-Point Radios

• Point-to-Multi-Point Radios

• VSAT & SATCOM

• Military & Space
