CHR2292_11 Datasheet, PDF (1/6 Pages) United Monolithic Semiconductors – 17-20GHz Integrated Down Converter

CHR2292
RoHS COMPLIANT
17-20GHz Integrated Down Converter
GaAs Monolithic Microwave IC
Description
LO
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
Q
communication systems. The backside of the
chip is both RF and DC grounds. This helps
simplify the assembly process.
GM
GB
I
The circuit is manufactured with a pHEMT ^VDM
process, 0.25µm gate length, via holes through ^VDL
the substrate, air bridges and electron beam GX
gate lithography.
VGA
It is available in chip form.
