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.

摘要翻译： 本发明的实施例提供了一种用于快速功率放大器控制的系统和方法。 该方法包括：在禁止固定增益放大器之前，在自动增益控制器最后调整增益之后，从自动增益控制器读取参考发射功率值，从固定增益放大器读取增益电平，并保存参考 在存储模块中传输功率值和增益级别; 在固定增益放大器使能之前，在自动增益控制器最后调整增益之后，将存储模块中保存的参考发送功率值写入自动增益控制器，并将保存在存储模块中的增益级别写入固定 增益放大器。 利用根据本发明的实施例的方法，固定增益放大器使能时的链路增益状态可以与固定增益放大器禁用之前的链路增益状态一致。 这确保了上行链路信号的发射功率稳定，质量好。
