CHR3694-QDG_11 Datasheet, PDF (1/18 Pages) United Monolithic Semiconductors – 37-40GHz Integrated Down converter

CHR3694-QDG
RoHS COMPLIANT
37-40GHz Integrated Down converter
GaAs Monolithic Microwave IC in SMD package
Description
The CHR3694-QDG is a multifunction chip,
which integrates a balanced cold FET mixer, a
time two multiplier, and a RF LNA including
gain control.
It is designed for a wide range of applications,
typically commercial communication systems.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes through
the substrate and air bridges.
It is available in lead-free SMD package.
A mirror version versus RF & LO access is
available as CHR3794-QDG.
