| 摘 要： | 针对OFDM信号对功放高峰值功率的要求,提出了工作在220～400 MHz的大功率功放模块设计的新方法.该方法结合ADS软件仿真分析,按仿真模型用QFX86射频同轴电缆自制了功率分配/合成网络,用该网络设计了一款输出峰值功率不小于300W的功放模块.该模块已成功应用于某电台中且工作良好.

| Abstract: | 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. |
