摘要
In this paper, a nonlinear model of a commercial 10-W laterally diffused metal oxide semiconductor (LDMOS) transistor for FM transmitters is identified. It is based on high-frequency small-signal measurements for the identification of both the parasitic network and the strictly nonlinear dynamic effects, whereas low-frequency large-signal measurements are exploited for the description of the dynamic I/V characteristics of the device above the cut-off of low-frequency dispersion. A validation of the proposed model is provided by using time-domain nonlinear measurements carried out at 40 MHz and 100 MHz. Copyright (C) 2013 John Wiley & Sons, Ltd.
