    摘要： Embodiments of the present invention provide a system and method for quickly power amplifier control. The method includes: before a fixed gain amplifier is disabled and after an automatic gain controller adjusts gain for the last time, reading a reference transmit power value from the automatic gain controller, reading a gain level from the fixed gain amplifier, and saving the reference transmit power value and the gain level in a storage module; and before the fixed gain amplifier is enabled and after the automatic gain controller adjusts gain for the last time, writing the reference transmit power value saved in the storage module into the automatic gain controller and writing the gain level saved in the storage module into the fixed gain amplifier. With the method according to the embodiments of the present invention, the link gain state when the fixed gain amplifier is enabled can be consistent with the link gain state before the fixed gain amplifier is disabled. This ensures that the transmit power of an uplink signal is stable with good quality.

    摘要： A transmission circuit operating at a high efficiency and a low distortion is provided. A signal generation section (11) generates a vector signal and an amplitude signal. A vector modulation section (13) performs vector modulation on the vector signal. An amplification section (15) amplifies the signal processed with the vector modulation. A signal processing section (12) performs predetermined signal processing on the amplitude signal and outputs the resultant signal. A regulator (14) controls a voltage to be supplied to the amplification section (15) based on the magnitude of the signal which is output from the signal processing section (12). The signal processing section (12) determines whether or not the amplitude signal exceeds a threshold value at an interval of a predetermined time period, selects a discrete value to be output based on the determination result, and outputs a signal having the selected discrete value.
