17-20GHz Integrated Down Converter

GaAs Monolithic Microwave IC

Description

The CHR2292 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.
