摘要： A transmitter that includes a feed forward amplifier amplifies an input signal to produce an amplified signal that includes a distortion component. The transmitter determines an error signal based on the input signal and the amplified signal and amplifies the error signal to produce an amplified error signal that includes an error signal distortion component. The transmitter combines the amplified error signal with the amplified signal to produce an output signal that includes the error signal distortion component and a portion of the amplified signal distortion component. The transmitter determines a distortion component of an attenuated version of the output signal and an energy of the determined distortion component. Based on the determined energy, the transmitter produces a control signal designed to minimize the energy of the distortion component of the attenuated output signal and thereby minimize distortion in the output signal.

摘要： A transmitter includes a feed forward amplifier that includes main signal path having a radio frequency (RF) power amplifier, a feed forward correction circuit, and a control circuit. An amplification of an input signal by the RF power amplifier produces an amplified signal that includes a distortion component. The feed forward correction circuit produces an error signal, which error signal is used to drive an error amplifier to produce an amplified error signal. In order to minimize a distortion component introduced to the amplified error signal by the error amplifier, the control circuit controls a peak power of the error signal based on a detected energy of an attenuated version of the error signal or based on the distortion component introduced to the amplified error signal by the error amplifier.

摘要： An amplifier includes a main amplifier circuit and at least one auxiliary amplifier circuit. Portions of an RF signal to be amplified are delivered to the main and auxiliary amplifiers. The auxiliary amplifier circuit is selectively operable to operate in combination with the main amplifier circuit, such as based on the level of the RF signal. At least one hybrid coupler circuit has input ports coupled with outputs of the main amplifier circuit and auxiliary amplifier circuit. The hybrid coupler circuit is operable to combine amplifier circuit output signals at a coupler first output port. A coupler second output port is terminated with one of an electrical short and an electrical open circuit.
