  • Patent number: 10003374
    Abstract: A wireless radio frequency transceiver system for Internet of Things includes: a wireless radio frequency transmission module and a wireless radio frequency receiving module. The wireless radio frequency transmission module is used to shape signal waveform of digital signals from the Internet of Things to modulate the digital signals to form modulated output signals, and adopt a self-mixing technique to increase voltage/current amplitude of the modulated output signals and reduce phase noise. The wireless radio frequency transmission module is further used to adopt a current reuse technique to amplify the voltage/current amplitude of the modulated output signals, and transmit the amplified modulated output signals through a first antenna to a wireless channel. The wireless radio frequency receiving module is used to detect carrier input signals received from a second antenna to obtain baseband signals and demodulate the baseband signals to form differential signals.
