The Keysight 11970Q (formerly Agilent Technologies), 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 11970Q extends the frequency range of the Keysight E4440A/46A PSA Series high-peformance spectrum analyzers, the E4407B ESA-E series portable spectrum analyzer, the Keysight 8560 E-series portable spectrum analyzers, the Agilent 8566B spectrum analyzer (used with the 11975A amplifier), and the Keysight 70000 modular measurement system (used with the 70907A/B external mixer interface modules).
Keysight 11970Q waveguide harmonic mixer units were previously manufactured by Agilent Technologies.
