CHR2293_11 Datasheet, PDF (1/4 Pages) United Monolithic Semiconductors – 20-24GHz Integrated Down Converter

CHR2293
RoHS COMPLIANT
20-24GHz Integrated Down Converter
GaAs Monolithic Microwave IC
Description
The CHR2293 is a multifunction chip which
integrates a LO X2 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.
