17-20GHz Integrated Down Converter
GaAs Monolithic Microwave IC
Description

The CHR2292 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 PM-HEMT
process, 0.25m gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
