Abstract：
The invention provides a transmitter and a wireless transceiver with the transmitter. The transmitter comprises a modulation module for generating an amplitude modulation signal and a frequency modulation signal; an oscillation module connected with the modulation module and used for generating a first local oscillation signal and a second local oscillation signal, the first local oscillation signal being a multi-phase local oscillation signal, and the second local oscillation signal being a frequency modulation local oscillation signal generated based on the frequency modulation signal; a first transmitting module working in a first frequency band mode and used for receiving the first local oscillation signal and the amplitude modulation signal and generating a first radio frequency signal after amplitude modulation and power amplification are carried out on the first local oscillation signal; and a second transmitting module working in a second frequency band mode and used for receiving the second local oscillator signal, carrying out logical operation on the local oscillator signal, synthesizing a frequency-doubled frequency-modulated signal, and carrying out power amplificationon the frequency-doubled frequency-modulated signal to generate a second radio frequency signal.
