Abstract
A large-signal nonlinear model was developed for a highly integrated quad-band (UGSM/EGSM/DCS/PCS) transmit front-end module (TX-FEM). The model includes separately validated large-signal nonlinear models of HBT amplifiers; large-signal nonlinear PHEMT switch models; large-signal nonlinear Si BJT PA controller model; largesignal EM-co-simulated model of a dual-band directional coupler-detector, including large-signal GaAs MESFET diodes; and Momentum or lumped element based model of the multi-chip module (MCM) level passive networks. To authors’ best knowledge this is the highest complexity large-signal transistor-based model of a radio sub-system ever reported.
