摘要： This disclosure relates to adaptively reducing the peak power of harmonic distortions as a function of the operating conditions for transmission communications. Specifically, the bias of the amplifier is adaptively increased to reduce harmonic distortions when a small fraction of the resource blocks are active.

摘要： The present disclosure relates to envelope power supply calibration of a multi-mode RF power amplifier (PA) to ensure adequate headroom when operating using one of multiple communications modes. The communications modes may include multiple modulation modes, a half-duplex mode, a full-duplex mode, or any combination thereof. As such, each communications mode may have specific peak-to-average power and linearity requirements for the multi-mode RF PA. As a result, each communications mode may have corresponding envelope power supply headroom requirements. The calibration may include determining a saturation operating constraint based on calibration data obtained during saturated operation of the multi-mode RF PA. During operation of the multi-mode RF PA, the envelope power supply may be restricted to provide a minimum allowable magnitude based on an RF signal level of the multi-mode RF PA, the communications mode, and the saturation operating constraint to provide adequate headroom.
摘要翻译：本公开涉及多模RF功率放大器（PA）的包络电源校准，以在使用多种通信模式中的一种进行操作时确保足够的余量。通信模式可以包括多种调制模式，半双工模式，全双工模式或其任何组合。因此，每个通信模式可以具有针对多模式RF PA的特定的峰均功率和线性要求。因此，每个通信模式可以具有对应的信封电源余量要求。校准可以包括基于在多模式RF PA的饱和操作期间获得的校准数据来确定饱和操作约束。在多模RFPA的操作期间，可以限制包络电源以基于多模式RF PA的RF信号电平，通信模式和饱和运行约束来提供最小允许幅度，以提供足够的余量。
