| CHM1193 K-Band Mixer GaAs Monolithic Microwave IC Description The CHM1193 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 Schottky diode process : 1 m Schottky diode device, air bridges, via holes through the substrate, stepper lithography. It is available in chip form. An electrically identical chip with a mirror drawing versus de LO side is available under the part number CHM1192. These two MMICs could be helpful in a TX, RX architecture module.
