CHA4664-QGG
RoHS COMPLIANT
5.5-16GHz Variable Gain Amplifier
GaAs Monolithic Microwave IC in SMD package
Description
The CHA4664-QGG is a variable gain
broadband three-stage monolithic amplifier.
It is designed for a wide range of applications,
typically commercial communication systems.
The circuit is manufactured with a Power
pHEMT process, 0.15µm gate length, via
holes through the substrate and air bridges.
