A transmitter ( ) includes a fractional N synthesizer, a baseband digital modulation stage coupled to the fractional N synthesizer in a first modulation mode, and a baseband I/Q modulation stage also coupled to the fractional N synthesizer and reusing the fractional N synthesizer in a second modulation mode. A method ( ) of operating a transmitter includes transmitting a first signal from a transmitter using the fractional N synthesizer and the baseband digital modulation stage to modulate the first signal according to a first wireless protocol. The method ( ) also includes transmitting a second signal from the transmitter using the baseband I/Q modulation stage and the fractional N synthesizer to modulate the second signal according to a second wireless protocol.
