26.5 to 40 GHz Flat frequency response Low conversion loss No bias or tuning adjustments 100 mW safe input level The Agilent 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 N9030A PXA high-performance signal analyzer to the A-Band (26.5 to 40 GHz). It is also fully compatible with other Agilent 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 11970A with the N9030A PXA (with Option EXM).
