Features:This is a double-balanced radio frequency mixer of RFin=1.5--4.5GHz, RFout=DC--1.5GHz, LO=312. 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. Double balanced mixers are more complex and require higher drive levels than unbalanced and single balanced designs. 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. Specifications: RFin=1.5--4.5GHz RFout=DC--1.5GHz LO=312 Noise Factor: 0.6dB LO/RF Isolation: 40dB Frequency Conversion Loss: 8.5dB 1dB Compression Point: 10dbm RF/IF Max. Input Power: 13DBM LO Max. Input Power: 27DBM Connector: Standard SMA-female Package Includes: 1 x Frequency Mixer
