CHR2296
RoHS COMPLIANT
36-40GHz Integrated Down Converter
GaAs Monolithic Microwave IC
Description
The CHR2296 is a multifunction chip which
integrates a LO time two multiplier, a
balanced cold FET mixer, and a RF LNA. It
is designed for a wide range of applications,
typically
commercial
communication
systems. The backside of the chip is both RF
and DC grounds. This helps simplify the
assembly process.
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.
