CHM1190 - United Monolithic Semiconductors

CHM1190 K Band Mixer

The CHM1190 is a balanced Schottky diode mixer based on a six quarter wave ring structure. It could be use in receiver or transmitter part. This circuit is manufactured with the BESMMIC process: 1 µm Schottky diode device, air bridges, via holes through the substrate, stepper lithography. An electrically identical chip with a mirror drawing versus de LO side.
