Abstract

Está relacionada con un dispositivo receptor que comprende un receptor (104) adaptado para la recepcion de senales de radio en dos bandas defrecuencia (FB1, FB2). Las senales de radio en una de las bandas de frecuencia (FB1) constituyen lasena l de comunicacion para un sistema de radio (AMPS,NMT) que tienen cierta separacion de canal, mientras que la segunda banda de frecuencia (FB2) constituye las senales de comunicacion para un segundosistema de radio (PCS1900, DCS1800,GSM) quetiene una segunda cierta separacion de canal. El receptor (104) incluye dos entradas (108, 111) cadauna proyectada para un sistema de radio que tiene diferentes bandas de frecuencia y separacion de canal. Par las senales de radioque oc urren en unaentrada (108), se realiza la mezcla del rango de radiofrecuencia RF directamente al rango de frecuencia de banda base. Para las senales de radioque ocurren en la segunda entrada (108) la mezcla del rango de frecuenciade ra dio al rango de frecuencia de banda base es realizado a través de un rangode frecuencia intermedia. Además el receptor (104) incluye una salida (112) proyectada para despachar senales de banda base a ambos sistemas de radio. Lasalida(112) está c onectada a la unidad de banda base la que es comun a los sistemas de radio. En la unidad de banda base, entre otras cosas, filtradopasabajos, deteccion y supresion de canales contiguos se realiza en la senal de radio recibida, laque ha sido m ezclada hacia abajo al rango de frecuenciade banda base.
