Abstract

The invention discloses a novel microwave intermodulation rectification circuit, which is characterized in that: a micro-strip rectification circuit is printed on a single-layer double-sided printed circuit board; an earth plate is respectively arranged on the bottom surfaces; a microwave source (1) is used for inputting and is connected with a blocking capacitor (2); a diode rectification micro-strip circuit part (3) is connected between the blocking capacitor (2) and a parallel earth capacitor I (4); an output end is branched into two paths; one path is output to a direct-current load I (6)through a low-pass filter circuit (5); the other path enters a recovery branch through a band-pass filter circuit (7); a recovery branch rectification part (8) is connected between the band-pass filter circuit (7) and a parallel earth capacitor II (9); and the recovery branch is output to a direct-current load II (10). By adopting an intermodulation differential frequency recovery branch, the problem of low-frequency energy loss caused by factors such as intermodulation and the like is solved, the defect of the intermodulation effect of the conventional rectification circuit is overcome effectively, and the radiofrequency energy-direct current conversion efficiency is increased.

Description

technical field [0001] The invention relates to a novel microwave inter-regulation circuit, which belongs to the field of microwave energy transmission. The microwave energy used for reception is converted into direct current. Background technique [0002] With the rapid development of the world economy, energy and environmental issues have become increasingly prominent. Various fields are actively responding to the energy development strategy, and technologies in the form of solar energy, wind energy, and bioenergy are currently the main solutions to energy problems. Restricted by factors such as the environment, climate, and region, most solutions have large and small flaws. At the beginning of the 20th century, microwave energy gradually entered the field of vision of researchers, and the "solar power station" scheme composed of aerospace technology and microwave energy transmission technology was realized. Microwave new energy has the advantages of high efficiency, no...
