Abstract
Un convertidor de frecuencia de radiofrecuencia a frecuencia intermedia de banda ancha que proporciona uso multiple de componentes de conversion de frecuencia pata muchos tipos diferentes de señales de radiofrecuencia de entrada. En ejemplos específicos, muchos tipos diferentes de señales para comunicacion, navegacion y para interrogacion son procesados a través de canales de conversion de frecuencia comunes al menos parcialmente. Tales señales de entrada de radiofrecuencia en el rango de aproximadamente 2 MHz a 2,000 MHz son convertidas a frecuencias de frecuencia intermedia de salida, tales como 1 MHz y 30 MHz, para procesamiento adicional en el receptor comun. Algunas señales de banda angosta, después de conversion a frecuencia intermedia, son sometidas a filtrado de centro desplazado en filtros de frecuencia intermedia, son sometidas a filtrado de centro desplazado en filtros de frecuencia intermedia de banda relativamente ancha. No se usan filtros de radiofrecuencia. Entre muchas etapas de conversion de frecuencia, solo es sintonizable una de las señales de oscilador local, pero es hecha sintonizable en pasos relativamente pequeños, precisos, utilizando un arreglo de doble circuito de asegurador de fase en el sintetizador de frecuencia.
