Abstract

"COMUTADOR DE ANTENA". Comutador de antena, compreendendo pelo menos um caminho de sinal, incluindo meio de amplificador (1) e meio de comutação (2), citado meio de amplificador (1) compreendendo um amplificador (4, 4') conectado a um primeiro indutor (5, 5') e a um primeiro capacitor (6, 6'), que é aterrado. Citado amplificador (4, 4') sendo alimentado por tensão via um segundo indutor (8, 8'), e citado meio de comutação compreendendo meio de isolamento de recepção (9, 9') que é conectado a um capacitor de desvio (10, 10'), conectado a uma antena (11) via filtro passa baixa (12, 12'). Uma primeira micro-tira (13, 13') é conectada ao citado capacitor de desvio (10, 10') e a meio de comutação CC (14, 15, 16; 14', 15', 16') no qual citado primeiro indutor (5, 5') e citado primeiro capacitor (6, 6'), juntamente com um transistor de saída curto circuitada do citado amplificador (4, 4'), constituem uma alta impedância no modo de recepção, deste modo não afetando o sinal de recepção, e citado meio de isolamento de recepção é um fio de sinal.
