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.

Main Features

■ 5.8GHz centre frequency

■ DC-50MHz IF bandwidth

■ Low noise figure

■ Low I/Q phase & amplitude unbalance

■ Chip size : 1.77 x 1.37 x 0.10 mm
