Abstract

ARRANJO DO FILTRO DE EXTREMIDADE DA ANTENA. Arranjo para a filtragem dos sinais transmitidos em um dispositivo de rádio usando duplex da divisão de freqüência. Em um radio transmissor onde o sinal transmitido é dividido para uma pluralidade de antenas (ANT1, ANT2, ANT3) que irradiam para diferentes setores, a filtragem necessária na transmissão é principalmente feita por um filtro de transmissão compartilhada (240) antes que o sinal transmitido seja dividido, O restante da filtragem é realizado separadamente em cada sinal de transmissão parcial (T1; T2; T3) no lado de transmissão reduzida (TXF1; TXF2; TXF3) do filtro duplex. Os filtros e o divisor (250) formam de preferência uma unidade de filtro integrada, onde estão conectados entre si por meio de elementos de acoplagem simples. O espaço necessário para os filtros da extremidade da antena do dispositivo de rádio é significativamente reduzido, sendo reduzidos na produção os custos de material e montagem da extremidade da antena.
