Abstract

CIRCUITO AMPLIFICADOR DE POTÊNCIA DE MODULAÇÃO POLAR E MÉTODO PARA PROPORCIONAR UMA FAIXA DINÂMICA AUMENTADA. Um circuito amplificador de potência de modulação polar inclui um circuito de controle (101) para determinar e proporcionar um sinal de seleção de carga (127), em que o sinal de seleção de carga (127) é determinado responsivo a um sinal de potência solicitado (119). Um amplificador de potência (113) é responsivo a um sinal de controle (141), para amplificação de um sinal RF (139) para produzir um sinal amplificado (145) possuindo um nível de potência de saída. Um circuito correspondente de impedância variável (117) é responsivo ao sinal de seleção de carga (127) para ajustar uma relação entre o nível de controle e o nível de saída de potência, para produzir um sinal amplificado de faixa ajustada (147).
