摘要
介绍了一种小功率(1 W)、2.45 GHz微波无线输电系统的发射端设计。直流电平经过锁相频率合成芯片ADF4360-0转换为S波段的2.45 GHz微波信号,ADF4360-0的寄存器配置由MSP430控制;2.45 GHz微波信号经过由功放芯片ERA-5SM及ADL5606组成的驱动级功率放大器将功率放大到1 W,加上喇叭天线即组成了小功率微波输电系统的发射端。利用矩形微带整流天线接收并整流微波信号,整流后的直流电平供给负载,便形成了完整的微波无线输电系统。详细分析了设计参数与方法,并进行了仿真及验证试验。
It introduced a transmitting terminal design of small power （l W）, 2.45 GHz micro-wave transmission system. A DC voltage level was transformed to a microwave signal of 2.45 GHz in S band with an MCU MSP430 of TI and a phase-locked fi＇e quency synthesis chip ADF4360-0 of ADI. The power of the micro wave was enlarged to 1 W by a driver stage amplifier which was consisted of two chips, ERA-5SM and ADL5606. Then the frequency synthesizer and the amplifier formed a transmitting termi nal with an horn antenna. After the microwave signal rectified to be a DC level which would be supplied to the load by a reetan gular microstrip rectifier antenna, it formed a basic microwave transmission system. It analyzed the parameters and methods of the design in detail, and carried through the simulation and verification test.
