Implementation of a Linearized Power Amplifier using a Adaptive Digital Predistorter
적응 디지틀 전치왜곡기를 이용한 선형화된 전력증폭기의 구현
Abstract
In this paper, the linearized power amplifier using digital adaptive predistorter is implemented in order to restrict spectral spreading and adjacent channel interference. The linearized systems is composed of a DSP56001 processor that executes predistortion in baseband. 90.deg. phase shifter, power splitter/combiner, quadrature modulator/demodulator of 360MHz band, and nonlinear amplifier.
