Abstract
A transmitter is adapted to be programmed to select an amplifier operating class for the transmitter out of a plurality of amplifier operating classes. The transmitter is also adapted to operate according to the selected amplifier operating class to communicate a signal to an antenna.
Claims15
A method comprising:
- selectively programming a transmitter to select an amplifier operating class for the transmitter from a plurality of amplifier operating classes, wherein the act of programming comprises selecting a Radio Frequency (RF) driving signal out of a plurality of RF driving signals to be provided to an output circuit of the transmitter;
- communicating a signal to an antenna using the transmitter programmed according to the selected amplifier operating class;
- using an output stage comprising a first transistor and a second transistor coupled to an output terminal of the transmitter to generate the signal to be provided to an antenna;
- and
- selectively routing the selected RF driving signal to the first and second transistors based on the selected amplifier operating class.
