Wideband test bench dedicated to behavioral modeling of non linear RF blocks with frequency transposition and memory

This paper presents a measurement scenario to extract the behavioral modeling of RF blocks exhibiting memory effects, mismatch and frequency transposition. The measurement principle is based on the use of a regular VNA setup and is applied here for the characterization and modeling of a Down-converter chain. The validation process of such a methodology is carried out with an experimental set-up based on transceiver architecture. It has been experimentally demonstrated that this measurement principle allows accurate model identification by performing a simple set of measurements. Extracted model proves the ability to provide a good prediction for complex communication signals.
