Abstract

<B>APARELHO ACOPLADOR DE FREQuêNCIA DE RáDIO ADEQUADO PARA UTILIZAçãO EM DISPOSITIVO DE COMUNICAçãO SEM FIO MULTI-BANDA<D> Um aparelho acoplador de freq³ência de rádio (RF) (312) adequado para utilização em um dispositivo de comunicação sem fio multi-banda (200) tem um dispositivo de terminação (316) e acopladores (314 e 315). Cada um dos acopladores (314 e 315) possui elementos de acoplamento de via de passagem (318 e 320) e elementos de acoplamento de via acoplada (319 e 321). Os elementos de acoplamento de via de passagem (318 e 320) passam um sinal RF que deve ser transmitido nas faixas de freq³ência respectivas (TX BAND 1, TX BAND 2) dentro das quais o dispositivo (200) opera. Elementos de acoplamento de via acoplada (319 e 321) acoplam os sinais RF passados pelos respectivos elementos de acoplamento de via de passagem (318 e 320). Os elementos de acoplamento de via acoplada (319 e 321) e o dispositivo de terminação (316) são acoplados em série, assim permitindo compatibilidade com um detector de potência RF (313) que utiliza um único diodo de detecção (322).
