CHR2296 Datasheet, PDF (1/5 Pages) United Monolithic Semiconductors – 36- 40GHz Integrated Down Converter

CHR2296
36- 40GHz Integrated Down Converter
GaAs Monolithic Microwave IC
Description
LO
The CHR2296 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 PM-HEMT
process, 0.25µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
