Power division rectifier network applied to high power microwave energy transmission system

This paper presents a power division rectifying network applied to a 5.8GHz ultra-large power microwave energy transmission system. The power division rectifier network comprises a high-power rectifier circuit and a 1-to-32 power division. The microwave energy received by the receiving antenna array is distributed to each rectifier circuit through the power divider. The synthesized DC power is obtained by connecting the rectifier circuit in parallel. Simulated results show that when the input microwave frequency is 5.8GHz, and the load is 120 ohms, the rectifier efficiency of a single rectifier circuit is above 60% within the input power from 27.3 dBm to 32.6 dBm. In addition, the highest rectification efficiency was 73.3% at 31.6dbm. For the power division rectifier network, when the input microwave frequency is 5.8GHz, and the load is 3Ω, rectifier efficiency is greater than 50% within the input power from 39.5dBm to 50.2dBm. At 48.7dBm, the rectification efficiency is 69.4%.
