5.8GHz I/Q Mixer
GaAs Monolithic Microwave IC
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 P­HEMT process : 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithogr aphy. It is supplied in chip form or in ceramic leadless chip carrier.
