Abstract
Un circuito amplificador para una senal de entrada de una disposición de comunicaciones celular, a una disposición celular que utiliza dicho circuitoy un método para proveer una senal amplificada mediante dicho circuito. Un circuitoamplifica dor (40) provee una senal amplificada en respuesta a unasenal de entrada. El circuito amplificador (40) incluye una red de entrada (44) para aplicar la senal de entrada a una seleccionada por lo menos una de unapluralidad de etapasamplificadoras. Un a red de salida (48) se provee para acoplar la senal amplificada desde una seleccionada por lo menos una etapaamplificadora. La etapa amplificadora apropiada se selecciona por medio de un circuito de control (56) enrespuesta a un valor de pot encia deseado de unasenal amplificada. Activando selectivamente sólo la etapa(s) amplificadora que es necesaria para proveer el nivel deseado de potencia de salida, laeficiencia CD aumentada se puede lograr enaplicaciones que requieren un amplificador que opera linealmente sobre un rango dinámico amplio.
