Abstract
Official abstract text for this publication.
An amplifier may include a predistorter receiving an input signal to generate a predistortion signal, a first converter receiving the predistortion signal to generate a preamplified signal, a power amplifier receiving the preamplified signal to generate an output signal based on the preamplified signal and the input signal, and a second converter sampling the output signal to generate a feedback signal. The predistorter may separately and independently generate a predistortion signal component for the in-phase input signal and a predistortion signal component for the quadrature input signal.
First claim
Opening claim text (preview).
I claim: 1. An amplifier, comprising: a predistorter receiving an input signal; a first converter receiving an output of the predistorter to generate a preamplified signal; a power amplifier receiving the preamplified signal to generate an output signal based on the preamplified signal; and a second converter sampling the output signal to generate a feedback signal; wherein the predistorter, based upon an in-phase component of the input signal and the feedback signal, intr…
