Abstract
A two-dimensional (2D) weighted nonlinear two-box (2D-WNTB) model is proposed for concurrent dual-band power amplifiers (PAs) with strong nonlinearity. The proposed model is composed of two cascaded blocks of mildly nonlinearity order of dynamic part and highly nonlinearity static part with weighted polynomial. In comparison with the previous models, the proposed model can reduce the computation complexity of the linearization with high modeling accuracy. Measurements were carried out for a deep biased class-AB PA. The results prove the effectiveness of the 2D-WNTB model.
