Study on 5.8 GHz band rectifying circuit for the inside wireless system of satellite

Abstract

  To reduce the weight of a satellite, an internal wireless system for satellites was proposed in a previous study. It is a system that can communicate between the subsystems by wireless communication modules. In this paper, we propose a complete internal wireless system using microwave wireless power transmission technology and present the design of a high efficiency rectifier circuit-based charge pump circuit. The conversion efficiency increases to 78 % at 30 mW in the simulation, and was about 71 % in the experiment. The output voltage is higher than 5 V at an optimum load of 1300 Ω.
