CHR2295 Datasheet, PDF (1/6 Pages) United Monolithic Semiconductors – 24-30GHz Integrated Down Converter

CHR2295
RoHS COMPLIANT
24-30GHz Integrated Down Converter
GaAs Monolithic Microwave IC
Description
LO
The CHR2295 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
I
communication systems. The backside of the
chip is both RF and DC grounds. This helps
simplify the assembly process.
GM
GB
Q
The circuit is manufactured with a PM-HEMT VDM
process, 0.25µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
