Abstract

"SISTEMA RECEPTOR UTILIZANDO CONVERSãO DEANALóGICO PARA DIGITAL EM RADIOFREQuêNCIA EMéTODO". Um receptor recebe sinais analógicos emradiofreq³ência (RF), e os sinais analógicos RF são convertidos emdomínio digital. Como tal, o receptor não requer estágio (s) deconversão de freq³ência antes da conversão analógica paradigital. Por exemplo, o receptor pode compreender pelo menos umaantena (s) que recebe sinais analógicos de radiofreq³ência (RF)em diferentes faixas de freq³ência. Os sinais analógicos RF sãofornecidos a um conversor analógico para digital (A/D) único, e oconversor A/D converte os sinais analógicos RF em diferentesfaixas de freq³ência em sinais digitais dentro da largura de faixaNyquist. Selecionando apropriadamente a taxa de amostragem doconversor A/D para os sinais analógicos RF, o conversor A/Dpode produzir réplicas de diferentes faixas de freq³ência dos sinaisanalógicos em porções de não-sobreposição da largura de faixa deNyquist.
