Radio frequency decoding circuit and decoding equipment

The utility model provides a radio frequency decoding circuit and a decoding device, the radio frequency decoding circuit is used for providing driving power for a radio frequency coil under the effect of a clock signal generator to sense a radio frequency source so as to generate a sensing signal and decode the sensing signal, and the decoding reliability is high. The radio frequency decoding circuit comprises a first reverse drive circuit, a second reverse drive circuit, a rectification circuit, a filter circuit, a charging and discharging circuit and a comparison circuit. One end of the first reverse drive circuit is connected with the clock signal generator, and the other end is connected with the first end of the radio frequency coil. One end of the second reverse drive circuit is connected with the clock signal generator, and the other end is connected with the second end of the radio frequency coil. The input end of the rectifying circuit is connected between the second end of the radio frequency coil
