Certain aspects of a method and system for using a phase locked loop (PLL) as a filter in a wideband crystalless polar transmitter may be disclosed. Exemplary aspects of the method may include modifying a clock signal generated by a voltage controlled oscillator within a phase locked loop. A modulated signal may be generated via a direct digital frequency synthesizer based on the modified clock signal. The modulated signal may be upconverted to a radio frequency (RF) signal utilizing a phase locked loop and the RF signal may be amplitude modulated. The phase locked loop may be enabled to filter the RF signal.
