Abstract

Un nivel de envoltura de un rendimiento de un amplificador de potencia de ganancia variable se detecta por un detector. Un nivel de envoltura de un rendimiento de un amplificador de potencia de ganancia variable detectado por el detector y una forma de onda de una señal de referencia que se genera de un generador de señal de referencia se comparan. Una ganancia del amplificador de potencia de ganancia variable se controla de conformidad con un rendimiento de comparacion. Durante la entrada de un rendimiento de transmision, la señal de referencia se eleva desde un nivel de tierra hasta un valor de reposo del detector o más, y se mantiene hasta un valor más elevado que el valor de reposo del detector. Después de que la señal de referencia admitio una escala de respuesta del circuito de realimentacion negativo, se elevo uniformemente a lo largo de una onda cuadrada de coseno. Durante la salida del rendimiento de transmision, la señal de referencia se reduce uniformemente hasta un valor proximo al valor de reposo del detector a lo largo de una onda cudrada de coseno y se mantiene a un valor proximo al valor de reposo del detector. Después de que el circuito de realimentacion negativo no respondio, la señal de referencia se reduce al valor del reposo del detector o menor.
