Abstract
Certain aspects of a method and system for a wideband polar transmitter may be disclosed. Aspects of the method may include polar modulating a plurality of signals by generating a plurality of modulated intermediate frequency (IF) signals corresponding to each of a plurality of wireless communication protocols within a transmitter that handles the plurality of wireless communication protocols. The generated plurality of modulated IF signals may be upconverted to a plurality of radio frequency (RF) signals. The plurality of RF signals may be combined and the combined plurality of RF signals may be amplitude modulated.
