CHA2292
17-24GHz 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.
