36-44GHz Multifunction (MFC) Down-Converter
GaAs Monolithic Microwave IC
Description
The CHR2297 is a multifunction chip (MFC)
which integrates a LO buffer amplifier, an IF
amplifier and a single cold FET mixer. It is
usable for down-conversion. It is designed for a
wide range of applications, from military to
Down converter
RF
LO
IF
commercial
communication
systems. The
backside of the chip is both RF and DC grounds.
This helps to simplify the assembly process.
The circuit is manufactured with a p-HEMT
process, 0.25µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
