ABSTRACT:
A hybrid transmitter includes first and second up-conversion modules, a combining module, and a power amplifier circuit. The first up-conversion module is operably coupled to generate a first up-conversion signal based on a normalized in-phase (I) symbol, an in-phase local oscillation, and phase or frequency information. The second up-conversion module is operably coupled to generate a second up-conversion signal based on a normalized quadrature (Q) symbol, a quadrature local oscillation, and the phase or frequency information. The combining module is operably coupled to combine the first and second up-conversion signals to produce a radio frequency (RF) signal. The power amplifier circuit is operably coupled to adjust amplitude of the RF signal based on amplitude information to produce an amplitude and phase modulated RF signal.
