HIGH EFFICIENCY AND HIGH LINEARITY ADAPTIVE POWER AMPLIFIER FOR SIGNALS WITH HIGH PAPR |
| 摘要 |
One embodiment of the present invention provides a system for controlling operations of a power amplifier in a wireless transmitter. During operation, the system receives a baseband signal to be transmitted, and dynamically switches an operation mode of the power amplifier between a high power back-off mode having a first power back-off factor and a normal mode having a second power back-off factor based on a level of the baseband signal. |

1. A method for controlling operations of a power amplifier in a wireless transmitter, comprising:
receiving a digital baseband signal; determining whether a power level of the received digital baseband signal exceeds a predetermined threshold; and if so,
placing the power amplifier in a high power back-off mode having a first power back-off factor; and if not,
placing the power amplifier in a normal mode having a second power back-off factor. |
