Abstract

Un aparato para recibir comunicaciones de radio frecuencia que comprende: una pluralidad de antenas para recibir senales de radio frecuencia; medios paraconvertir las senales de radio frecuencia a senales de frecuencia intermedia; medios para convertir hacia abajo digitalmente una de las senales digitales auna senal de banda base de frecuencia intermedia, que incluyen medios para seleccionar una de las senalesdigitales; y medios para procesar la senal de banda basede frecuencia intermedia para recuperar uno de una pluralidad de canales de comunicacionesallí contenidos. El convertidor hacia abajo comprende una pluralidad de convertidores hacia abajo conmutados digitales, cada uno de una pluralidad deconvertidores hacia abajo conmutados digitales siendo acoplados a medios para convertir las senales de frecuencia intermedia a senales digitales y a losmedios para procesar la senal de banda base de frecuencia intermedia.An apparatus for receiving radio frequency communications comprising: a plurality of antennas for receiving radio frequency signals; means for converting radio frequency signals to intermediate frequency signals; means for digitally converting one of the digital signals to an intermediate frequency baseband signal, including means for selecting one of the digital signals; and means for processing the intermediate frequency baseband signal to retrieve one of a plurality of communication channels contained therein. The down converter comprises a plurality of digital switched down converters, each of a plurality of digital switched down converters being coupled to means for converting the intermediate frequency signals to digital signals and the means for processing the intermediate frequency baseband signal .
