Abstract: A method and apparatus for dynamically adjusting the impedance between a transmitter's power amplifier (PA) and antenna to efficiently transfer power from the PA to the antenna. The impedance between the PA and the antenna is adjusted based on power level measurements and/or PA direct current (DC) consumption measurements, depending on whether the PA is a linear PA or a switch-mode PA. In another embodiment, a hybrid PA including a first stage linear PA and a second stage switch-mode PA is implemented in a transmitter. The hybrid PA selectively connects the output of the first stage linear PA to one of the input of the second stage switch-mode PA and the output of the hybrid PA, depending on the output power level of the first stage linear PA, the output power level of the hybrid PA, or a requirement indicated by a transmit power control (TPC) command.

Abstract: Un metodo y aparato para ajustar dinamicamente la impedancia entre el amplificador de potencia (PA) y la antena del transmisor, para transferir eficientemente potencia desde el PA a la antena. La impedancia entre el PA y la antena se ajusta en base a las mediciones del nivel de potencia y/o mediciones de consumo de corriente directa (DC) del PA, dependiendo si el PA es un PA lineal o un PA de modo conmutado. En otra modalidad, en el transmisor se implementa un PA hibrido que incluye un PA lineal de primera etapa y un PA de modo conmutado de segunda etapa. El PA hibrido conecta selectivamente la salida del PA lineal de primera etapa a una de la entrada del PA de modo conmutado de segunda etapa y la salida del PA hibrido, dependiendo del nivel de potencia de salida del PA lineal de primera etapa, el nivel de potencia de salida del PA hibrido, o un requerimiento indicado por la orden de control de potencia de transmision (TPC).
