摘要: This disclosure relates to radio frequency (RF) amplification devices and methods for amplifying an RF input signal. To set the quiescent operating level of the RF output signal, a bias signal to be applied to the RF input signal is received prior to amplifying the RF input signal. The bias signal is amplified to generate the RF output signal at the quiescent operating level and a feedback signal is received that is indicative of the quiescent operating level of the RF output signal. Prior to amplifying the RF input signal, the bias signal level of the bias signal is adjusted such that the quiescent operating level is set to a reference signal level based on the feedback signal level. This allows for adjustments to be made to the quiescent operating level and maintain the quiescent operating level at a desired value.

摘要: A charge pump of a PA bias power supply, PA bias circuitry, and a process to optimize efficiency of the PA bias power supply are disclosed. The charge pump operates in one of multiple bias supply pump operating modes, which include at least a bias supply pump-up operating mode and a bias supply bypass operating mode. The process prevents selection of the bias supply bypass operating mode unless a DC power supply voltage is adequate to allow the PA bias circuitry to provide minimum output regulation voltage at a specified current. Otherwise, the bias supply pump-up operating mode is selected. The charge pump operates more efficiently in the bias supply bypass operating mode than in the bias supply pump-up operating mode; therefore, selection of the bias supply bypass operating mode, when possible, increases efficiency.
