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.
