Abstract
SE PRESENTA UNA DISPOSICION DE UN CIRCUITO PARA CONMUTAR ENTRE (CONMUTACION DE TRANSITO) SEÑALES DE RF. LAS SEÑALES DE DISTINTAS FUENTES DE SEÑALES DE RF SE CONMUTAN MEDIANTE RUTAS DIODICAS CONTROLADAS (D1-D3, D6-D8) EN DONDE LOS DIODOS DE CAPACITANCIAS (D4, D5, D9, D10) SE UTILIZAN PARA ALCANZAR UN VALOR ALTO DE DESACOPLAMIENTO ENTRE LAS FUENTES EN EL ESTADO DE DESACTIVADO.
