Disclosed is a receiver. The receiver comprises an antenna, a bandpass filter, and a frequency mixer that are electrically connected in series, a local oscillator electrically connected to the frequency mixer, also comprising: a diplexer, where the diplexer is used for separating and outputting high and low frequency components in a signal outputted by the frequency mixer; and, a rectifier unit, where the rectifier unit is used for converting the high frequency component outputted by the diplexer and storing in a battery. The present invention introduces the diplexer into the receiver, losslessly separates a baseband signal from a carrier signal of a same path, respectively performs information decoding and energy acquisition, implements simultaneous information and energy transfers, obviates the need for altering an existing modulation technique, has great compatibility and a simple and reasonable structure, and is easy to implement. |
