Digital Power Amplifier (DPA) System and Digital Dougherty Power Amplifier (DDPA) System

摘要

A digital power amplifier (DPA) system comprises a power amplifier (PA) circuit having a control input and an output that produces an output signal, an input interface, an output interface, a memory that stores adaptive control algorithms, and this memory. An adaptive control circuit comprising a processor that executes instructions in association with it based on an adaptive control algorithm, the input interface receiving an input state signal and an output signal of a PA circuit, and an adaptive control algorithm having an input state signal and an output. It includes an adaptive control circuit that obtains control parameters of a control signal transmitted from an output interface to a control input in order to control the operation of the PA circuit according to the signal.
