CHR3693-QDG
RoHS COMPLIANT
21-26.5GHz Down converter
GaAs Monolithic Microwave IC in SMD package
Description
The CHR3693-QDG is a multifunction part,
which integrates a balanced cold FET mixer, a
I
time two multiplier, and a RF LNA. It is
designed for a wide range of applications,
typically commercial communication systems.
Q
The circuit is manufactured with a PM-HEMT
process, 0.25µm gate length, via holes
through the substrate and air bridges.
