摘要
A novel microwave (MW) rectifier based on a diode array is presented in this paper. The diode array composed with sixteen HSMS-282 Schottky diodes is applied to enhance the MW input power. The proposed configuration improves the rectifier power capacitance from 20 dBm level of a single-diode rectifier up to 30 dBm level. The presented design is to use a diode array to replace a single diode without significant modification on the original rectifying circuit. When the input power is between 23 dBm and 33 dBm and the load is at hundred Ohm level, microwave to direct current (MW-DC) conversion efficiency above 60% is realized. The DC output voltage of the rectifier achieves 20.4V at a load 600 Ohm, when the input MW power is at 30 dBm. The MW-DC conversion efficiency reaches 69.4% in this situation. The maximum power that the rectifier can handle is greater than 33 dBm. The measured temperature of the rectifier shows the power consumption distributed among the diode array evenly.
