| 摘要 |
A method and apparatus for improved power control of a radio frequency power amplifier achieved by limiting the maximum power of the radio frequency signal and varying the power of the radio frequency signal according to one or more power control feedback signals. In particular, the maximum power is limited by limiting the average current of the RF signal to a predetermined maximum value, despite the changing amplitude of the RF signal, thereby limiting the power of the radio signal and preventing the power control signals to the power varying circuit from being overwhelmed and/or maintaining stability.
