Abstract: The present disclosure relates to a polar phased-array transmitter and a mobile terminal. One example mobile terminal includes a baseband chip, the polar phased-array transmitter, and an antenna array. The baseband chip is configured to generate a quadrature digital baseband signal. The polar phased-array transmitter is configured to perform quadrature-to-polar conversion on the quadrature digital baseband signal to generate n amplitude signals and n phase signals, separately perform phase modulation and phase shifting on the n phase signals by using a local oscillator signal to obtain n phase modulation signals, and perform amplitude modulation and power amplification on the n phase modulation signals by using the amplitude signals to obtain n radio frequency signals. n is a natural number greater than 1. The antenna array is configured to obtain the n radio frequency signals from the polar phased-array transmitter, and transmit the n radio frequency signals.

Abstract: The present invention discloses a transmitter, a receiver, and a method for receiving and transmitting a radio frequency signal, and relates to the field of radio communications technologies, which can perform carrier recovery and generation at a front end of a radio frequency circuit, thereby reducing a running cost of a baseband chip. The method includes: generating, by an amplitude discriminator/phase detector according to an intermediate-frequency analog signal, a signal amplitude pulse signal/signal phase pulse signal that is not corrected; generating, by a bit error matrix corrector, an amplitude/phase correction control signal; correcting, by the amplitude discriminator/phase detector, the signal amplitude pulse signal/signal phase pulse signal according to the amplitude/phase correction control signal; and converting, by an amplitude code generator/phase code generator, a corrected pulse signal into a corresponding digital code. The present invention is applicable to receiving/transmitting a radio frequency signal.

Abstract: A radio frequency transmitter is provided. The radio frequency transmitter includes a radio frequency front-end and a control circuit. The radio frequency front-end includes a current source set, a compensation circuit, and a matching network. The compensation circuit may compensate for a difference of load impedance between N current source subsets in the current source set. Therefore, an impedance mismatch of the current source set may be alleviated, and a power loss of the current source set may be avoided. This helps improve the efficiency of the radio frequency transmitter.
