Abstract

Un transmisor (107) incluye circuitos amplificadores (203) y circuitos de control (215, 217, 219) para desviar a los circuitos amplificadores (203) de tal forma que operan lo más cercanos a la saturacion con una eficiencia mejorada. La señal de voltaje de compuerta (213), que proporciona un desvío de compuerta, está conectado a los circuitos amplificadores (203) y varían dinámicamente por medio de los circuitos del procesador (219) como respuesta al valor del voltaje de control del amplificador (211) conectado a los circuitos amplificadores (203). El voltaje de control del amplificador (211), que tiene un valor para mantener la potencia de salida de los circuitos amplificadores (203) en un constante, se produce por medio de circuitos integrados (217) como respuesta a una comparacion de la señal de salida de potencia detectada (216) producida por medio de los circuitos de deteccion (215) y de la señal de control de salida de potencia (218) producida por los circuitos del procesador (219). La eficiencia se realiza variando dinámicamente la señal de voltaje de compuerta (213) hasta su magnitud mayor de tal forma que los circuitos amplificadores (203) pueden operar tan cercanos a la saturacion como sea posible mientras que, al mismo, tiempo mantienen una potencia de salida constante.
