25-35GHz Single Side Band Mixer

Self biased

GaAs Monolithic Microwave IC

Description

The CHR2294 is a multifunction chip (MFC)

which integrates a self biased LO buffer

amplifier and a sub-harmonically balanced

diodes mixer for 2LO suppression and image

rejection. It is usable for both up-conversion

and down-conversion. It is designed for a

wide

range

of

applications,

typically

commercial

communication

systems

for

broadband local access. The backside of the

chip is both RF and DC grounded. This helps

to 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.
