CHM1191

CHM1191 K Band Mixer GaAs Monolithic Microwave IC Description The CHM1191 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 is available under the part number CHM1190. These two MMICs could be helpful in a TX, RX architecture module. It is available in chip form.
