20GHz Integrated-LO RF Mixer


SKU: MX20000 Category:


THE most compact and economical microwave integrated-LO-mixer on the planet. 

The MX20000 is a wideband high-performance general purpose microwave double-balanced mixer with integrated 12GHz – 22GHz Local Oscillator. LO frequency can be set with front controls, USB commands, or the provided windows PC application. Using its ultra-low noise internal reference source, the LO signal has extremely low phase noise. The MX20000 makes a convenient upconverter or downconverter by eliminating the need for extra cabling and a separate bulky, expensive, high-frequency signal source.
