Negative amplitude polar transmitter

A polar transmitter includes a phase monitoring unit for monitoring input modulating data. When a phase transition exceeds a phase transition threshold, the phase monitor unit can signal an amplitude negation unit to invert the amplitude data coupled to the polar amplifier. The phase monitoring unit can also add an offset to the phase data that is provided to a frequency synthesizer. In another embodiment, when the phase transition threshold is exceeded, the phase monitoring unit can trigger inverting differential frequency data coupled to the polar amplifier. In one embodiment, the phase offset and the amplitude negation are applied until a second phase transition value exceeding the phase transition threshold is detected. If such an event is detected, then the input amplitude data is no longer inverted and the phase offset value is no longer added to the modulating data.
