摘要： A communication device (300) having an RF power amplifier stage with a Cartesian feedback loop is provided. The loop has forward paths whose outputs are combined to form an output signal that is fed back to a single feedback path. Each forward path has a common path with a filter (304, 324) that filters the overall loop response and a unique split path. The main and auxiliary split paths have a power amplifier (319, 340) and carry signals respectively of lower and higher frequencies. The auxiliary amplifier (319) is faster than the main amplifier (340). Different phases of the carrier signal are used during upconversion such that the overall phase response through the split paths is equal. Instability recovery problems introduced by higher-order loop filters are mitigated by baseband loop filters (1300) with switchable order. Upon detecting instability, the loop filter order is reduced and is subsequently increased after eliminating the unstable operation.
摘要翻译：提供具有笛卡尔反馈回路的RF功率放大器级的通信设备（300）。该回路具有其输出被组合以形成反馈到单个反馈路径的输出信号的前向通路。每个前向路径都有一个带有过滤器（304,324）的公共路径，该过滤器对整个循环响应和唯一的拆分路径进行过滤。主分路和辅助分路具有功率放大器（319,340），分别承载较低和较高频率的信号。辅助放大器（319）比主放大器（340）更快。在上转换期间使用载波信号的不同相位，使得通过分离路径的整体相位响应相等。由高阶环路滤波器引入的不稳定性恢复问题可以通过可切换顺序的基带环路滤波器（1300）来缓解。在检测不稳定性时，消除不稳定操作后，环路滤波器阶数减小并随后增加。

摘要： Embodiments of the present invention enable a blended control approach to generate a desired output waveform in an outphasing-based system. Embodiments of blended control according to the present invention combine outphasing with bias and/or amplitude control to yield an accurate, practical, and producible system with substantially comparable performance to that of a theoretical ideal outphasing system, but without the isolation and accuracy requirements of outphasing alone.

摘要： A radio frequency signal (205) is sampled and the sample is conveyed to a video detector (220). The detected envelope amplitude is sent to an envelope tracking circuit (280), a comparator (230), and an envelope tracking and gate biasing circuit (240). Based on the instantaneous value of the envelope amplitude, the comparator (230) selects one of the available supply voltages (340) via switch drivers (270). The selected one of the available supply voltages (340) is adjusted by the envelope tracking circuit (280) and the resulting voltage output (284) is supplied to the drains of the power amplifiers (390), thus enabling operation near saturation. As the instantaneous value of the envelope amplitude increases, the comparator (230) selects higher supply voltages (340) which increases the voltage conveyed to the power amplifiers (390), thereby increasing their power output. In order to maintain constant gain performance, the envelope tracking and gate biasing circuit (240) modifies the gate bias inversely with the changes in the drain voltage.
