16-24GHz Low Noise, Variable Gain Amplifier

GaAs Monolithic Microwave IC

Description

The CHA2292 is a high gain four-stage

monolithic low noise amplifier with variable gain.

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 helps simplify the assembly

process.

The circuit is manufactured with a PM-HEMT

process, 0.25µm gate length, via holes through

the substrate, air bridges and electron beam

gate lithography.

It is available in chip form.
