Abstract
Disclosed in the present disclosure is a cross-band passive backscatter circuit, which belongs to the technical field of radio frequency transceivers. The cross-band passive backscatter circuit includes: an uplink including an input radio frequency antenna, a matching network, a carrier enhancement circuit, a carrier frequency division circuit, a cross-frequency backscatter module, a digital baseband, and an output reflection antenna; a power management unit including a rectifier, a bandgap reference, and a linear voltage regulator; and a downlink including a downlink demodulation circuit. In the present disclosure, frequency division output of a high-frequency carrier obtained by an on-chip low-power frequency divider and a high-frequency carrier are utilized to complete cross-band higher-frequency backscatter. Compared with a traditional cross-band communication technology, the design of a multi-band local oscillator is avoided, cross-band backscatter communication is directly realized, and power consumption and hardware overhead are reduced.
