Abstract

CIRCUITO DE RADIOFREQUÊNCIA E DISPOSITIVO ELETRÔNICO. A presente invenção fornece um circuito de radiofrequência e um dispositivo eletrônico. O circuito de radiofrequência inclui um transceptor de radiofrequência com uma primeira porta de transmissão, um primeiro módulo de radiofrequência conectado a um primeiro conjunto de antena, um segundo módulo de radiofrequência conectado a um segundo conjunto de antena e um primeiro interruptor. Um primeiro terminal de entrada do primeiro interruptor é conectado à primeira porta de transmissão e dois terminais de saída do primeiro interruptor são respectivamente conectados aos dois módulos de radiofrequência. No caso em que o primeiro interruptor está em um primeiro estado, a primeira porta de transmissão é conectada condutivamente ao primeiro módulo de radiofrequência; ou, no caso em que o primeiro interruptor está em um segundo estado, a primeira porta de transmissão é conectada condutivamente ao segundo módulo de radiofrequência.
