CHA2294
RoHS COMPLIANT
35-40GHz Low Noise, Variable Gain Amplifier
GaAs Monolithic Microwave IC
Description
The CHA2294 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 to simplify the
assembly process.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
