Modeling power amplifiers with antenna mismatch

The paper presents an approach for behavioral level power amplifier modeling with antenna mismatch. The derived model is based on device large signal S-parameter measurements of a commercially available W-CDMA power amplifier. The measurement setup is described in detail and the model validity is verified by comparing measured and simulated adjacent channel power ratios (ACPR). The measured and simulated ACPR show very good agreement and match at the nominal drive level to within 2 dB over the maximum output VSWR ratings.
