CHR0100a
5.8GHz I/Q Mixer
GaAs Monolithic Microwave IC
Description
The CHR0100a is a single chip MMIC
including an I/Q mixer and a RF gain block
that minimises the overall conversion loss of
the receiver and provides the RF signal to
the mixer through a power divider.
The circuit is manufactured with the P-
HEMT process : 0.25µm gate length, via
holes through the substrate, air bridges
and electron beam gate lithography.
It is supplied in chip form or in ceramic
leadless chip carrier.
