CHR2295_15 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
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 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.
