CHA3694-QDG
RoHS COMPLIANT
31-40GHz Variable Gain Amplifier
GaAs Monolithic Microwave IC in SMD package
Description
The CHA3694-QDG 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.
It is available in lead-free SMD package.
