CHM1290REF - United Monolithic Semiconductors

CHM1290REF 20-30GHz SUB-HARMONICALLY PUMPED MIXER

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 c.
