Abstract:
A radio frequency (RF) transmitter front-end includes a digital to analog conversion module and a power amplifier module. The digital to analog conversion module is coupled to convert amplitude information into analog amplitude adjust signals when a first mode is active and is coupled to convert power level information into analog power level signals when a second mode is active. The power amplifier module is coupled to amplify first phase modulated RF signals in accordance with the analog amplitude adjust signals to produce first outbound RF signals when the first mode is active and is coupled to amplify second phase modulated RF signals in accordance with the analog power level signals to produce second outbound RF signals when the second mode is active.
