Abstract

FILTRO ÁGIL DE FREQUÊNCIA COM O USO DE UM FILTRO DIGITAL E FILTRAGEM DE BLOQUEIO DE BANDA. A presente invenção refere-se a um filtro com base em processador de sinal digital de RF híbrido para arquiteturas de rádio de multibandas, sistemas capazes de reorganizar o espectro e rádio definido por softwares. A múltipla filtragem de entalhe ágil de frequência de baixa perda em RF onde uma grande faixa dinâmica sai na entrada do filtro entre os sinais é a faixa de bloqueio ou a passa banda. Na saída do amplificador de potência a invenção pode ser usada para atenuar os desvios ou ruído dentro das bandas com limitações de emissão estrita. Antes da saída do amplificador de baixo ruído, a invenção pode ser usada para atenuar os bloqueadores e o ruído de transmissor fora da passa banda do receptor.
