Abstract

APARELHO PARA TRANSMISSãO E RECEPçãO DE MúLTIPLAS FREQUêNCIAS DE RáDIO SIMULTANEAMENTE ATRAVéS DE UMA úNICA ANTENA. Trata-se de um aparelho para transmissão e recepção de múltiplas freqtiências de rádio simultaneamente através de uma única antena. O aparelho compreende um aparelho de combinação de sinais de transmissores configurado para acoplamento comunicativo com uma pluralidade de transmissores, em que o aparelho de combinação de sinais de transmissores é configurado para produzir como saida um sinal de transmissão baseado em quaisquer sinais recebidos da pluralidade de transmissores. O aparelho também inclui pelo menos um duplexador de sinais de transmissão/recepção acoplado ao aparelho de combinação de sinais de transmissores e configurado para provisão do sinal de transmissão para uma antena, em que a antena recebe um sinal de rádio-freqúência (RF) em chegada. Adicionalmente, o aparelho inclui um aparelho de separação de sinais acoplado ao pelo menos um duplexador de sinais de transmissão/recepção e configurado para receber o sinal de RF em chegada e fornecer o sinal de RF em chegada a pelo menos um receptor. O pelo menos um duplexador de sinais de transmissão/recepção é adicionalmente configurado para provisão do sinal de RF em chegada ao aparelho de separação de sinais, e para limitar um acoplamento direto do sinal de transmissão para o aparelho de separação de sinais.
