CHM1298-99F
55-65GHz Single Side Band Mixer
Description
GaAs Monolithic Microwave IC
The CHM1298 is a multifunction chip (MFC)
which integrates a LO buffer amplifier and a
sub-harmonically balanced diode mixer for
2LO suppression and image rejection. It is
usable both for up-conversion and down-
conversion. It is designed for a wide range of
applications, from military to commercial
communication systems. 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.
