Amplifier with reduced harmonic distortion

摘要

A method and apparatus are disclosed for a configurable amplifier. When operating in a first operating mode, the configurable amplifier may amplify a communication signal and may cancel or attenuate a second harmonic component associated with the communication signal. When operating in a second operating mode, the configurable amplifier may amplify the communication signal without cancelling or attenuating the second harmonic component associated with the communication signal.

主权项

1. A configurable amplifier, comprising:
a first processing chain to generate a first up-converted communication signal; a second processing chain to generate a second up-converted communication signal; and a summing node to generate an output signal of the configurable amplifier based, at least in part, on the first up-converted communication signal and the second up-converted communication signal, wherein:
when the configurable amplifier is to operate in a first mode, the second up-converted communication signal is a substantially ninety degree phase-shifted version of the first up-converted communication signal; andwhen the configurable amplifier is to operate in a second mode, the second up-converted communication signal is substantially similar to the first up-converted communication signal.
