An Analytical Model for Improvement of Linearity and Efficiency of RF Linear Power Amplifiers for Radar Systems

Amir Al-Mslmany, Caiyun Wang, and Qunsheng Cao

Abstract—Power amplifier is the key component in radar systems, so linearity and efficiency is the most important parameters in order to maintain the performance of power amplifier, based on matlab curve fitting toolbox an analytical model for improvement of linearity and efficiency of radio frequency (RF) linear power amplifiers (PAs) is introduced. This model simplifies the traditionally complicated methods of analysis of RF PA. According to a change of the direct current (DC) bias as a function of the alternative current (AC) input signal of RF linear PA the linearity and efficiency can be improved.

Index Terms—AC and DC analyses, ADS, biasing, efficiency linearity.
