摘要： A charge pump of a power amplifier (PA) bias power supply and a process to prevent undershoot disruption of a bias power supply signal 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 pump-up operating mode from the bias supply bypass operating mode before charge pump circuitry in the charge pump is capable of providing adequate voltage to prevent undershoot disruption of the bias power supply signal.

摘要： Power amplifier (PA) control circuitry and PA bias circuitry are disclosed. During one slot of a multislot transmit burst from radio frequency (RF) PA circuitry, the PA control circuitry selects one PA bias level of the RF PA circuitry and the RF PA circuitry has one output power level. The RF PA circuitry has a next output power level during an adjacent next slot of the multislot transmit burst. If the one output power level exceeds the next output power level by more than a power drop limit, then the PA control circuitry maintains the one PA bias level during the adjacent next slot. If the one output power level significantly exceeds the next output power level, but by less than the power drop limit, then the PA control circuitry selects a next PA bias level, which is less than the one PA bias level, during the adjacent next slot.

摘要： A power amplifier (PA) envelope power supply, which provides an envelope power supply signal to radio frequency (RF) PA circuitry, and a process to prevent undershoot of the PA envelope power supply is disclosed. The process includes determining if an envelope control signal to the PA envelope power supply has a step change from a high magnitude to a low magnitude that exceeds a step change limit. Such a step change may cause undershoot of the PA envelope power supply. As such, if the step change exceeds the step change limit, the envelope control signal is modified to use an intermediate magnitude for period of time. Otherwise, if the step change does not exceed the step change limit, the envelope control signal is not modified.

摘要： The present disclosure relates to amplitude based pre-distortion calibration of an RF communications terminal, such as a cell phone, by transmitting a first standard RF transmit burst from the RF communications terminal to an RF test instrument, which assimilates the first standard RF transmit burst. A calibration control system extracts information regarding the first standard RF transmit burst from the RF test instrument; determines amplitude based distortion of the RF communications terminal using the extracted information; determines amplitude based pre-distortion calibration information using the determined amplitude based distortion; and calibrates the RF communications terminal using the amplitude based pre-distortion calibration information. By using a single-shot transmit burst, calibration times may be minimized. To calibrate the RF communications terminal at multiple transmit frequencies, multiple single-shot transmit bursts may be used, such that each single-shot transmit burst is at a different calibration frequency.
