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.
