11970A Waveguide Harmonic Mixer

• Flat frequency response
• Low conversion loss
• No bias or tuning adjustments
• 100 mW safe input level

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.
