Abstract

UN RECEPTOR DE RADIO SATELITE RECIBE SEÑALES DE UNA INSTALACION RECEPTORA DE4 SATELITES QUE ABARCA UNO O VARIOS CAMBIADORES DE FRECUENCIA. LOS CAMBIADORES DE FRECUENCIA PUEDEN ESTAR SOMETIDOS POR EJEMPLO, POR INCLUENCIA DE TEMPERATURA, A UNA CORRIENTE DE FRECUENCIA QUE MEDIANTE UNA CONEXION AFC EN EL RECEPTOR DE RADIO SATELITE TRANSMITE UNA CONEXION DEMOLADORA QUE NO PUEDE SER COMPARADA. SEGUN EL INVENTO SE FORMA UN OSCILADOR DE SOBRECARGA PROVISTO DE MEZCLADOR COMO OSCILADOR DE SOBRECARGA PLL (44) DETERMINABLE EN UNA ONDA GRANDE O PEQUEÑA. LA CONEXION AFC (1) Y UNA CONEXION DE VALORACION DE SEÑALES DE SINCRONIZACION (40) ESTAN UNIDAS CON UNA CONEXION DE VALORACION DE SEÑALES DE SINCRONIZACION (40) ESTAN UNIDAS CON UNA CONEXION DE MANDO (34), MEDIANTE EL QUE EL OSCILADOR DE SOBRECARGA PLL (44) FUERA DEL CAMPO DE REGULACION DE LA CONEXION AFC (1), SI NO RECONOCE LAS SEÑALES DE SINCORNIZACION ES DETERMINADO EN ONDA GRANDE Y RECONOCIENDO LAS SEÑALES DE SINCRONIZACION EN ONDA PEQUEÑA HASTA EL CAMPO DE REGULACION DE LA CONEXION AFC (1). EL RECEPTOR DE RADIO SATELITE DESCRITO ES APROPIADO PARA SU INSTALACIONES EN RECEPTORES DE SATELITES QUE POR LA VARIEDAD DE CAMBIOS DE FRECUENCIA MUESNTRAN UN SUMARIO DE DESVIACIONES DE LA FRECUENCIA NOMINAL DE RECEPCION O EN INSTALACIONES INDIVIDUALES PRIVADAS EN LAS QUE POR MOTIVOS DE SU COSTO NO SE INSTALO UN ESTABILIZADOR DE ALTA FRECUENCIA.
