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. CHM1290REF 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).

CHM1290REF is manufactured with a PMHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. CHM1290REF is supplied in a new SMD-type leadless chip carrier.
