HP 11970V Waveguide Harmonic Mixer, 50 GHz to 75 GHz

The HP 11970V waveguide mixer is a general-purpose harmonic mixer employing a dual-diode design to achieve flat frequency response and low conversion loss. These are achieved without external dc bias or tuning stubs. Manual operation and computer-controlled hardware operation are simplified because mixer bias and tuning adjustment are not required. The HP 11970V extends the frequency range of the HP 8560 E-series portable spectrum analyzers, the HP 8566B spectrum analyzer (used with the HP 11975A amplifier), and the HP 70000 modular measurement system (used with the HP 70907A/B external mixer interface modules).
