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

The Keysight 11970Q 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 N9030A PXA high-performance signal analyzer to the Q-band (33 to 50 GHz). It is also fully compatible with other Keysight spectrum analyzers including: the E4440A/46A/48A PSA (with Option AYZ), the E4407B ESA-E (with Option AYZ), the 856xEC, the 8566B (with a preamplifier), and the 7000 modular analyzer (with the 70907A/B external mixer interface module).

An external diplexer is required to connect the 11970Q with the N9030A PXA (with Option EXM). The recommended diplexer can be purchased from Keysight as model number N9029AE13, or from OML, Inc as model number DPL.313B.
