  • Radio frequency transmitter
    Patent number: 10917127
    Abstract: A radio frequency transmitter includes a digital-to-analog converter, a passive network, two buffers, a frequency mixer, and a power amplifier. Two output ends of the digital-to-analog converter are respectively coupled to two input nodes of the passive network, and the two output ends of the digital-to-analog converter are respectively coupled to input ends of the two buffers. Output ends of the two buffers are respectively coupled to two input ends of the frequency mixer. An output end of the frequency mixer is coupled to an input end of the power amplifier. An output end of the power amplifier is coupled to an antenna. The passive network is configured to perform filtering processing on an input current signal, and convert the current signal into a voltage signal.
