| 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300 W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 O
FDM signal,a novel design method for high power amplifier operating at 220
～400 MHz is
proposed. Based on the simulation analysis by ADS software,QFX
86 Radio Frequency (RF) coaxial cable is used to build up a power distribution/
s
ynthesis
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. |
