CHR2295

24-30GHz Integrated Down Converter

United Monolithic Semiconductors 

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.
