The RF power amplifier stage is usually the final active block of any electronic system that is transmitting RF power. Relatively low power RF signals are amplified to produce a more powerful signal ...

Linearity Testing RF power amplifier (RFPA) nonlinearities introduce third-order intermodulation distortion (IMD) to the amplifier output signal when driven by a multitone input signal.

A novel block-oriented time-delay neural network (BOTDNN) model for dynamic nonlinear modeling and digital predistortion (DPD) of RF power amplifiers (PAs) is proposed. The proposed model consists of ...

Abstract: A novel method of constructing nonlinear kernel functions for digital predistortion (DPD) of radio frequency (RF) power amplifiers (PA), excited with signals under dynamic resource block (RB ...
