Design of X-band rectifier circuit with large dynamic range
A 10 GHz microstrip rectifier circuit with high efficiency and wide input dynamic range is designed in this paper.The circuit is designed using GaAs Schottky diodes MA4E1317 produced by MACOM.By adding a microstrip line in series before the diode,the input impedance of the diode changes smoothly with the variation of input power.Additionally,a stepped impedance transformer is introduced at the input port to achieve better power matching at multiple power levels,thereby achieving a large power dynamic range.Test results show that at a frequency of 10 GHz,with a load of 600 Ω and an input power of 17 dBm,the rectification efficiency is 76.5%.The input power dynamic range for over 50%rectification efficiency reaches 14 dB(from 6 to 20 dBm).The high efficiency and large dynamic range of this rectifier circuit make it highly promising in the field of wireless energy transfer for mobile microwave targets.
