Abstract

A receiver is provided, wherein the receiver includes an antenna, a band pass filter and a frequency mixer electrically connected in sequence, and a local oscillator electrically connected with the frequency mixer, and further includes: a diplexer for separating and outputting high and low frequency components in a signal outputted by the frequency mixer; and a rectifying unit for converting the high frequency component outputted by the diplexer into direct current energy and storing the direct current energy in a storage battery. The diplexer introduced in the receiver separates a baseband signal and a carrier signal in the same path losslessly, respectively conducts information decoding and energy capture, implements simultaneous information and energy transfer, and does not need to change the present modulation technology, therefor having strong compatibility, being reasonable and simple in structure, and being easy to implement.

Claims

1. A receiver, comprising an antenna, a band pass filter and a frequency mixer electrically connected in sequence, and a local oscillator electrically connected with the frequency mixer, wherein the receiver further comprises:

a diplexer for separating and outputting high and low frequency components in a signal outputted by the frequency mixer;

a rectifying unit for converting the high frequency component outputted by the diplexer into direct current energy and storing the direct current energy in a storage battery; and

a first low pass filter for conducting low pass filtering the low frequency component outputted by the diplexer to obtain a baseband information signal.

2. The receiver of claim 1, wherein:

the rectifying unit comprises a diode and a second low pass filter electrically connected in sequence;

the diode rectifies the high frequency component outputted by the diplexer; and

the second low pass filter filters higher harmonics in signals rectified by the diode to obtain direct current energy and output the direct current energy to a storage battery for storage.

3. The receiver of claim 1, wherein:

the receiver further comprises a low noise amplifier;

the input end of the low noise amplifier is connected with the output end of the band pass filter; and
