Abstract

This paper introduces a new technique which allows us to measure the admittance conversion matrix of a two-port device, using a large signal vector network analyzer. This method is applied to extract the conversion matrix of a 0.25 um PHEMT, driven by a 4.8 GHz signal, at different power levels, using an intermediate frequency of 600 MHz. A discussion of the up-and down-conversion is provided. For the first time a vectorial large signal characterization is extended to the large signal harmonics and intermodulation products.
