Abstract
APARELHO PARA MELHORAR A RECEPçãO EM UM SISTEMA COM MúLTIPLOS TRANSMISSORES E RECEPTORES. é apresentado um aparelho para transmitir e receber freqtiências múltiplas com uma única antena. O aparelho inclui um primeiro transmissor configurado para transmitir sinais em uma primeira freq{iência para uma antena, e pelo menos um receptor configurado para receber sinais em uma segunda freqüência da antena. O aparelho ainda inclui um filtro de entalhe acoplado ao primeiro transmissor e configurado para rejeitar urna componente na segunda freqüência a partir de um sinal transmitido pelo primeiro transmissor.
