摘　　要：随着高频技术的发展,微波能量传输系统中常采用更高的频率,为了使整流天线能得到高输出电压,并且减少系统体积,降低装置成本,设计了一种C波段微波无线电能传输系统的发射端。直流电平经过锁相环合成芯片转换为C波段微波信号。该信号经过由驱动级功率放大芯片和高功率放大芯片组成的功率放大器,将功率放大到6 W,加上喇叭天线即组成了C波段微波无线电能传输系统的发射端。详细分析设计参数与方法,并利用ADS软件进行仿真验证。该系统具有极高的工作频率,省略了许多高频系统中的倍频部分,简化了系统结构,降低了装置成本。With the development of high frequency technology,the higher frequency is used in microwave energy transmission systems.In order to get the high output voltage of rectifying antenna,reduce the volume of the system and lower the cost ofthe device,a transmitting terminal of microwave wireless power transmission system working in C band was designed.The DCvoltage is converted into microwave signal of C band through the phase-locked loop synthesis chip.The signal is amplified to6Wthrough the power amplifier composed of driver stage power amplifying chip and high-power amplifying chip,and the horn antenna is added to form the transmitting terminal of microwave wireless power transmission system working in C band.The design parameters and method are analyzed in detail,and verified with ADS software simulation.The system has extremely high workingfrequency,and can omit the frequency doubling segment in many high frequency systems;the method has simplified the structure of the system and reduce the device cost.
