Abstract :
A new modified Bessel-Fourier (MBF) nonlinear RF power amplifier (PA) memoryless behavioral model is proposed. The accuracy and behavioral prediction performance especially of its low third order model is better than the best published low order models in use today. Besides inheriting all the key properties of the BF model, surpassing its low-order and matching its high-order accuracy and performance, the new model comes with two additional attributes of `margin of reliability´ beyond the dynamic range set by the extraction measurements and model order `monotonic extensibility´.
