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 pHEMT
process, 0.25µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form.
