采用4只HSMS 282肖特基二极管阵列,对大功率微波整流电路进行了研究.构造了基于微带线结构的2.45 GHz高效微波整流电路,将微波整流单元电路的输入功率提升到33 dBm.仿真和实验结果表明,在一定微波输入功率的条件下,整流电路在负载较大范围内变化时保持了高整流效率.通过在不同微波输入功率和负载下进行测量,发现当输入微波功率为27.0～31.7 dBm之间变化时,最高整流效率均达到了60％以上,当微波输入功率为30 dBm时,微波整流电路效率达到了63.3％.%A microwave rectifier is an essential part of a microwave power transmission system. In order to maintain high rectifying efficiency at a high input microwave power level, a novel microstrip microwave rectifier based on diode array is presented in this paper. The microwave input power was enhanced to 33 dBm at 2. 45 GHz. The simulated and measured results show the proposed microwave rectifier presents a reasonable efficiency at given input microwave power, while the load varies within a certain range. The rectifying efficiency is higher than 60% when the input microwave power is between 27 dBm to 31. 7 dBm. The maximum efficiency of 63. 3% is achieved at 30 dBm input microwave power.
