Energy supply module, system and product using radio frequency energy

Abstract

The invention relates to an energy supply module using radio frequency energy. The energy supply module comprises a radio frequency chip for configuring a radio frequency signal, a power amplification chip for amplifying the radio frequency signal and an antenna for transmitting the amplified radio frequency signal, and the duty ratio of the radio frequency chip is set to be 50%-100%, and the modulation mode is set to be OOK / FSK / GFSK; The energy supply module does not depend on a wireless charging module, long-distance power supply is realized by sending a carrier signal which is high in duty ratio and is not limited by a modulation mode as radio frequency energy, only a radio frequency chip with a proper radio frequency band needs to be selected when the wireless power supply device is applied, the power supply distance can be remarkably increased by applying the mode of the wireless power supply device, tests show that the power supply distance reaches 3 meters when the transmitting power is 33 dBm, and the problem that wireless charging is large in limitation and difficult to popularize and apply is solved.

Description

Technical field [0001] The present invention relates to the technical field of wireless power supply modules, and more particularly to a power supply module, system and article utilizing radio frequency energy. Background technique [0002] Wireless power is a new type of power supply, which saves the connection line, making it more convenient to power; [0003] However, the wireless charging scheme currently used is also detrimental wireless charging chip, and the wireless charging chip has a defect with a large power supply distance limit, usually the power supply distance must not exceed 50 mm, it is difficult to promote application; [0004] The existing conventional radio frequency signal transmission source is a modulated signal, and the frequency needs to be calibrated and the frequency error has a high requirements. Otherwise, the modulation signal will not be recognized by the receiving end, it is difficult to use in the wireless charging scheme as function Module is use...

AI Technical Summary

Problems solved by technology

[0003] However, the current wireless charging scheme still relies on a dedicated wireless charging chip, and the wireless charging chip has a defect that the power supply distance is relatively large. Usually, the power supply distance cannot exceed 50 mm, which is difficult to promote and apply;

[0004] The existing conventional radio frequency signal transmission sources all use modulation signals, the frequency needs to be calibrated and has high requirements for frequency error, otherwise the modulation signal will not be recognized by the receiving end, and it is difficult to be used as a function in the wireless charging solution Mod use
