The Keysight Agilent 11970W is a high-performance waveguide harmonic mixer designed to extend the frequency range of compatible spectrum analyzers into the W-band (75 to 110 GHz). It employs a dual-diode design that achieves exceptionally flat frequency response and low conversion loss without the need for an external DC bias or tuning stubs, simplifying both manual and automated test setups.
