A Novel Design Method for UHF High Power Amplifier Module
Liu Ji-lin · Telecommunication Engineering · 2012
According to the requirement of high peak power of Power Amplifier(PA) for OFDM signal,a novel design method for high power amplifier operating at 220～400 MHz is proposed.Based on the simulation analysis by ADS software,QFX86 Radio Frequency(RF) coaxial cable is used to build up a power distribution/ synthesis network and this network is employed to develop a PA module with peak power no less than 300 W.This module has been successfully applied in a radio set and it perferms well.
