Patent ID: 7974356

Claim:
A hybrid transmitter comprises: a baseband processing module operable to: convert input data into an in-phase (I) symbol and a quadrature (Q) symbol; generate phase information based on the I and Q symbols; and generate amplitude information based on the I and Q symbols; a first up-conversion module coupled to the baseband processing module and operable to normalize the I symbol to produce an amplitude-normalized in-phase (I) symbol and to generate a first up-conversion signal based on the amplitude-normalized I symbol, an in-phase local oscillation and the phase information, the first up-conversion module adjusting a phase of the amplitude-normalized in-phase (I) symbol using the phase information to produce the first up-conversion signal; a second up-conversion module coupled to the baseband processing module and operable to normalize the Q symbol to produce an amplitude-normalized quadrature (Q) symbol and to generate a second up-conversion signal based on the amplitude-normalized Q symbol, a quadrature local oscillation, and the phase information, the second up-conversion module adjusting a phase of the amplitude normalized quadrature (Q) symbol using the phase information to produce the second up-conversion signal; a combining module coupled to the first up-conversion module and the second up-conversion module and operable to combine the first and second up-conversion signals to produce a radio frequency (RF) signal; and a power amplifier circuit coupled to the combining module and operable to adjust an amplitude of the RF signal based on the amplitude information to produce an amplitude and phase modulated RF signal.
