Abstract

unidades de amplificação de potência e métodos são fornecidas, as quais usam um combinador e um sinal auxiliar para alimentar o amplificador de potência (pa) com um sinal que previne ou reduz a operação de estágios de amplificação mais altos durante períodos desligados do sinal de rf recebido. a saída do pa é distribuída através de um circuito de correspondência de saída configurado para passar o sinal de rf e atenuar o sinal auxiliar; e o combinador combina o sinal de rf e o sinal auxiliar através de respectivos filtros para gerar o sinal de entrada de rf para o pa. um gerador de sinal auxiliar pode ser configurado para gerar o sinal auxiliar em relação ao sinal de rf como tendo um espectro de frequência mais baixo que uma frequência de rf de corte. o consumo de energia mais baixo resultante, particularmente no caso de sinais de rf de baixo ciclo de trabalho, reduz aquecimento, permite uso de bateria mais longo e aumenta o desempenho de confiabilidade.
