55-65GHz Low Noise / Medium Power Amplifier

GaAs Monolithic Microwave IC

Description

The CHA2159 is a four - stage low noise and

medium power amplifier. It is designed for a wide

range

of

applications,

from

military

to

commercial

communication

systems. The

backside of the chip is both RF and DC

grounded. This simplifies the assembly process.

The circuit is manufactured with a pHEMT

process, 0.15µm gate length, via holes through

the substrate, air bridges and electron beam

gate lithography.

It is supplied in chip form.

Main Features
