    摘要: The band pass filter includes at least first and second band pass filters. A selector receives at least one signal, and supplies the signal to one of the first and second band pass filters. A controller controls the selector based on a frequency of the signal.

    摘要: An input signal is modified to compensate for amplifier memory effects by combining at least two versions of the input signal, each version of the input signal being offset in time with respect to one another. More specifically, an RF input signal is split into at least two split signals, a different delay is applied to each split signal, and the delayed, split signals are combined to obtain a modified input signal.
