20-30GHz SUB-HARMONICALLY PUMPED MIXER

GaAs Monolithic Microwave IC

Description

The CHM1290 is a MFC which integrates a self

biased

LO

buffer

amplifier

and

a

sub-

harmonically diodes mixer for 2LO suppression

It is usable both for up-conversion and down-

conversion. It is designed for a wide range of

applications,

typically

commercial

communication systems for broadband local

access (LMDS). 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, capacities over via

holes, via holes through the substrate, air

bridges and electron beam gate lithography.

It is available in chip form.
