Abstract :
This paper presents, for the first time, wideband large signal network analyzer (LSNA) measurements used to extract a large-signal behavioral model of an RF amplifier. The methodology together with some important issues concerning the data processing are discussed. The procedure is illustrated by an example of a packaged buffer amplifier for wireless applications. We performed qualitative and quantitative analysis of the model´s accuracy by means of wideband large-signal measurements and large-signal metrics, respectively. Additionally, we compare these results with those obtained from a behavioural model based on narrowband LSNA measurements
