Abstract

CIRCUITO DE COMPENSACION DEL NIVEL DE SALIDA DE RADIOFRECUENCIA PARA UN TRANSMISOR DE RADIO. COMPRENDE UN DISPOSITIVO COMPENSADOR DE SEÑAL DE RADIOFRECUENCIA CON UN SEGUNDO AMPLIFICADOR DE POTENCIA PARA AMPLIFICAR UNA SEÑAL DE RADIOFRECUENCIA DE ENTRADA HASTA UN NIVEL DE TRANSMISION QUE CORRESPONDE A UN NIVEL DE TENSION DE CONTROL AUTOMATICO DE ALIMENTACION DE ENTRADA, UN SEGUNDO CIRCUITO DE TRANSMISION ACOPLADO A UN TERMINAL DE SALIDA DEL SEGUNDO AMPLIFICADOR PARA RADIO-TRANSMITIR LA SEÑAL AMPLIFICADA, UN SEGUNDO CIRCUITO DE CONTROL DE SALIDA DE TRANSMISION PARA SUMINISTRAR UNA SEGUNDA TENSION DE CONTROL AUTOMATICO DE ALIMENTACION AL SEGUNDO AMPLIFICADOR EN RESPUESTA A LA TENSION DE NIVEL DE SALIDA PREDETERMINADO INTRODUCIDA, UNA SEGUNDA BATERIA, Y UN SEGUNDO CIRCUITO DE MANDO DE ALIMENTACION PARA REGULAR LA TENSION DE LA SEGUNDA BATERIA A LA TENSION DE NIVEL PREDETERMINADO Y SUMINISTRARLA COMO TENSION OPERACIONAL DE LAS RESPECTIVAS UNIDADES EN EL DISPOSITIVO COMPENSADOR, Y UN CIRCUITO DECONEXION PARA CONECTAR LA TENSION DE NIVEL DE SALIDA PREDETERMINADO AL SEGUNDO CIRCUITO DE CONTROL DE SALIDA DE TRANSMISION Y UNA SALIDA DEL PRIMER CIRCUITO DE TRANSMISION A UNA ENTRADA DEL SEGUNDO AMPLIFICADOR, Y AL MISMO TIEMPO, PROPORCIONAR UNA SEÑAL DE DETECCION DE CONEXION AL PRIMER CIRCUITO DE CONTROL DE SALIDA DE TRANSMISION.
