The WHMB-12-0003 from Farran is a Waveguide Harmonic Mixer with an RF frequency from 60 to 90 GHz and an IF frequency range from DC to 2000 MHz. It requires an LO drive level of +17 dBm and has a conversion loss of 32 dB. This mixer integrates an LO/RF diplexer to separate the LO and IF frequencies at the LO/IF common port. It can be used with Keysight and Rohde & Schwarz’s spectrum analyzers for frequency extension applications. This mixer is available in a module that measures 37 x 41 x 26 mm with SMA-female connectors and WR-12 (UG-387/UM) waveguide test flange. It is suitable for use in spectrum analysis, mm-Wave instrumentation, signal processing, and phase-locked loop applications.
