UMS CHR3693

CHR3693-99F
RoHS COMPLIANT
21-26.5GHz Integrated Down converter
GaAs Monolithic Microwave IC
Description
LO
The CHR3693-99F is a multifunction chip,
which integrates a balanced cold FET mixer,
a time two multiplier, and a RF self biased
LNA.
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, air bridges and
electron beam gate lithography.
It is available in chip form.
