Abstract

UN AMPLIFICADOR DE POTENCIA DE ALTA FRECUENCIA (10) AMPLIFICA SEÑALES PERIODICAS EN FORMA DE BARRIDOS DE HF. LA SALIDA DE POTENCIA DEL AMPLIFICADOR SE AJUSTE MEDIANTE UN CIRCUITO CERRADO DE CONTROL (20) QUE PRODUCE UNA SEÑAL DE CONTROL EN RESPUESTA A UNA COMPARACION HECHA ENTRE UN VALOR DE PUNTO AJUSTADO (BV) Y LA SALIDA DE POTENCIA ACTUAL (PUT) Y APLICA LA SEÑAL AL AMPLIFICADOR DE POTENCIA. EL CIRCUITO CERRADO DE CONTROL INCLUYE UN AMPLIFICADOR DIFERENCIAL (25). UN CIRCUITO DE CORRECCION (40) MIDE EL VOLTAJE DE SALIDA DEL AMPLIFICADOR DIFERENCIAL DURANTE UN PERIODO DE TIEMPO (T1 A T2) ANTES DE CADA BARRIDO DE HF Y ALMACENA EN UNA MEMORIA (C) UNA MAGNITUD PROPORCIONAL A ESTE VOLTAJE DE SALIDA. DURANTE EL SIGUIENTE BARRIDO DE HF, SE USA ESTA MAGNITUD PARA INTRODUCIR EN EL CIRCUITO CERRADO DE CONTROL UNA MAGNITUD DE CORRECCION (UKORR) PARA LA CORRECCION DE LOS VOLTAJES DESAJUSTADOS (UOFF) QUE SE PRODUCEN EN EL CIRCUITO CERRADO DE CONTROL.
