80–360 GHz very wide band millimeter wave network analyzer

Abstract

An extension to a 20 GHz HP8510C Network Analyzer has been built for wideband measurements between 80 and 360 GHz. Improvements relative to the first version [1], [2] include new harmonic mixers, and an active doubler. Dynamic ranges up to 60 dB in transmission and 50 dB in reflection are obtained up to 280 GHz, with more than 50 GHz instantaneous bandwidth using waveguide calibration. Detection with a 30 dB dynamic range is obtained at 320 – 360 GHz. Time domain measurements give spatial resolution down to 2 mm.
