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 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.
