Linearization of Efficiency-Optimized Dynamic Load Modulation Transmitter Architectures

In this paper, a detailed linearization procedure for dynamic load modulation (DLM) transmitter architectures is proposed for the first time. Compared with the conventional single-input/single-output digital predistortion (DPD) approach used with traditional power amplifiers (PAs), the proposed line...
