Abstract

The invention provides a radio frequency module. The radio frequency module comprises a receiving sub-module used for receiving signals; the extraction sub-module is connected to the output end of thereceiving sub-module and is used for extracting signals; the calibration sub-module is connected to the output end of the extraction sub-module and is used for calibrating the phase of the extractedsignal; and the modulation sub-module is connected to the output end of the calibration sub-module and is used for modulating signals. The radio frequency module adopts an active load modulation technology, and can output a load modulation signal with enough high power, so that an oscillation component does not need to be added, and the volume of the radio frequency module is reduced; and the loadmodulation signal can be stabilized at a relatively large power value, so that the amplitude of the load modulation signal is stable, the power is higher, and the load modulation signal is not easilyinterfered by the outside.

Description

technical field [0001] The invention belongs to the technical field of radio frequency, and in particular designs a radio frequency module. Background technique [0002] Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets through radio signals and read and write related data without the need to establish mechanical or optical contact between the identification system and specific targets . [0003] With the passage of time and the application of RFID technology, the theory of RFID has been enriched and perfected. Single-chip electronic tags, multi-electronic tag identification (anti-collision), wireless readable and writable, long-distance identification of passive electronic tags, and RFID adapted to high-speed moving objects are becoming a reality (freeway toll collection). The future large-scale application of RFID will be unlimite...
