Caracterización de la conversión Vdd-AM y Vdd-PM en la etapa de modulación clase-E de un transmisor polar

Abstract

In this paper, an experimental procedure is proposed for accurate characterizing the Vdd-to-AM and Vdd-to-PM nonlinearities in a class E amplifier, aimed to be employed as modulating stage in a polar wireless transmitter. Based on the obtained results, a detailed study of the device characteristics limiting the modulator performance is made.
