Abstract

"TRANSCEPTOR RF DIGITAL COM MODOS DE GERAçãO DE IMAGEM MúLTIPLA". As modalidades reveladas se referem a um circuito (100) de freqüência de rádio (RF) digital que cria um sinal em uma faixa desejada em um espectro de freqüência. O circuito RF (100) compreende conjunto de circuitos (104) que produz um primeiro sinal (105) modulado de dados de amostra tendo uma primeira freqüência e uma primeira taxa de relógio de dados de amostra. Um modulador (108) de amostrador ascendente recebe o primeiro sinal modulado de dados de amostra e produz um segundo sinal (109) modulado de dados de amostra tendo uma segunda freqüência e uma segunda taxa de relógio de dados de amostra. O circuito RF (100) pode compreender também conjunto de circuitos (112) que recebe o primeiro sinal modulado de dados de amostra e o segundo sinal modulado de dados de amostra e distribui um dentre o primeiro sinal (105) modulado de dados de amostra e o segundo sinal (109) de dados de amostra para processamento adicional dependendo de qual sinal modulado de dados de amostra exibe características desejáveis para um determinado ambiente de operação.
