United Monolithic Semiconductors 

CHM1290REF

20-30GHz SUB-HARMONICALLY PUMPED MIXER

GaAs Monolithic Microwave IC in SMD leadless package

Description

The monolithic microwave IC (MMIC) in the

package is a multi-function chip which

integrates a self biased LO buffer amplifier

and a sub-harmonic diode mixer for 2LO

suppression. It is usable both for up- and

down-conversion and it is designed for a

wide range of applications, typically

commercial communication systems for

broadband local access (LMDS).

The circuit is manufactured with a PM-

HEMT process, 0.25µm gate length, via

holes through the substrate, air bridges and

electron beam gate lithography. It is

supplied in a new SMD-type leadless chip

carrier.
