HMC950

v03.0611

General Description

Features

Functional Diagram

The hmC950 is a four stage GaAs phemT mmiC

4 watt power Amplifier which operates between 12

and 16 Ghz. The hmC950 provides 28 dB of gain,

+37 dBm of saturated output power, and 23% pAe

from a +7V power supply. The hmC950 exhibits

excellent linearity and is optimized for high capacity

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

it is also ideal for 13.75 to 14.5 Ghz Ku Band VsAT

transmitters as well as sATCom applications. 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: +37 dBm @ 23% pAe

high output ip3: +44.5 dBm

high Gain: 28 dB

DC supply: +7V @ 2400 mA

no external matching required

Die size: 3.23 x 3.45 x 0.1 mm

Typical Applications

The hmC950 is ideal for:

• Point-to-Point Radios

• Point-to-Multi-Point Radios

• VSAT & SATCOM

• Military & Space
