Abstract

If the large signal network analyser [W. Van Moer, Y. Rolain, A large-signal network analyzer: why is it needed? IEEE Microwave Magazine,Vol. 7, No. 6, pp. 46-62, 2006] is used to measure the waveforms present at the device ports, two additional calibration steps, a power and a phase calibration, are needed besides the classical linear SOLT-calibration. The aim of this paper is to estimate and validate a parametric black-box model for a crystal detector. This detector is used as a reference element to calibrate the phase distortion of a LSNA operating under narrow band modulated excitation.
