CHR2294
RoHS COMPLIANT
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.
Up-conversion Supradyne mode
IF = 1.2GHz 4V / 60mA
It is available in chip form.

the quality of the external quadrature combiner.
A bonding wire of typically 0.1 to 0.15 nH will improve the accesses matching.
