ABSTRACT:
An RF mixer combines electrical and structural aspects to create a more efficient device. Diodes are coaxially mounted within two conductive tubes which form shields. The respective diode or diodes associated with each of the tubes are cross-connected at the LO port to the tube associated with the other diode or diodes. A capacitor compensates the inductance associated with the outer surfaces of the tubes. At their other ends, the tubes are coupled to ground and the diodes are coupled to an RF/IF bandsplitting network.
