5.8GHz Medium Power Amplifier

GaAs Monolithic Microwave IC

Description

The CHA5215a is a MMIC multifunction

integrating

a

3-stage

medium

power

amplifier, a gain control and an output

detector. A high saturated output power

allows

a

linear

operating

point

for

multichannel communication applications.

The output power can be controlled thanks

to the combination of a detected output

voltage and an important gain control

dynamic range.

The circuit is manufactured with a standard

0.7µm

implanted

power

MESFET,

air

bridges, via holes through the substrate

and

electron

beam

gate

lithography

process. It is supplied in chip form

or in

ceramic flat-pack package.

Main Features

■ Wide operating frequency range

■ High saturated output power

■ High linearity

■ High gain

■ High dynamic gain control
