Description: This is a double-balanced radio frequency mixer of RFin=1.5--4.5GHz, RFout=DC--1.5GHz. It has both its inputs applied to differential circuits, so that neither of the input signals and only the product signal appears at the output. Radio frequency microwave receiver down-conversion, with double-balanced microwave diodes inside, high reliability, high conversion efficiency: 8.5dB loss, high isolation between local oscillator and RF input: 40dB. This mixer has good isolation at RF and IF ends relative to LO end, so it does not demand more about IF filter. Standard SMA female connectors are suitable for connecting most devices.
