Research and Design of 27.12 MHz Power Amplifier Based on ADS
Advanced Design System(ADS)software is used to perform DC scanning,stability analysis,load-pull,and source-pull simulation of the power device SD2931-10,to determine the static operating point of the RF ampli-fier when operating in Class AB,improve the stability of the amplifier,and obtain the best input and output imped-ance.The Smith Chart tool is used to establish L-shaped input and output matching circuits,and the circuit per-formance parameters are verified by harmonic balance simulation.The basic circuit unit of the power amplifier is designed,and the RF amplifier topology is determined according to the principle of parallel connection of the two-port network,and the corresponding power synthesis circuit is designed to achieve a maximum power output of 2000 W.
