Abstract
This work presents an efficient neural networkbased power amplifier (PA) behavioral model across operating voltage (OV) and carrier frequency nonlinear states. This model can reduce the original training dataset size to 8.45% and the time to train to 2% when compared to a behavioral model (BM) trained for all the states. For proof-of-concept, this model is validated with laboratory data over a range of carrier frequencies from 2600 MHz to 3600 MHz, and OV levels from 3.5 V to 5 V.
