The Keysight 11970A 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 11970A extends the frequency range of the Keysight E4440A/46A/48A PSA Series high-performance spectrum analyzers, the E4407B ESA-E Series portable spectrum analyzer, the Keysight 8560 E/EC-Series portable spectrum analyzers, the 8566B spectrum analyzer (used with the 11975A amplifier), and the 70000 modular measurement system (used with the Keysight 70907A/B external mixer interface modules).
