CHR2391 Datasheet, PDF (1/6 Pages) United Monolithic Semiconductors – 12-16GHz Integrated Down Converter

CHR2391
RoHS COMPLIANT
12-16GHz Integrated Down Converter
GaAs Monolithic Microwave IC
Description
The CHR2391 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 to
simplify the assembly process.
The circuit is manufactured with a PM-HEMT
process, 0.25µm gate length, via holes through
the substrate and air bridges.
It is available in chip form.
