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

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.
