Abstract
Diplexor dual para telefonía celular GSM y DCS. Diplexor que opera simultáneamente en las bandas de telefonía celular GSM (890 MHz - 960 MHz) y DCS (1710 MHz - 1880 MHz), realizado en tecnología microstrip o stripline, a partir de la interconexión de dos filtros paso banda interdigitales formados por líneas de transmisión acopladas de longitud eléctrica 90º a la frecuencia central de las bandas de GSM y DCS, respectivamente.Dual diplexer for GSM and DCS cell phones. Diplexer that operates simultaneously in the GSM (890 MHz - 960 MHz) and DCS (1710 MHz - 1880 MHz) cell phone bands, carried out in microstrip or stripline technology, from the interconnection of two interdigital band-pass filters formed by lines of coupled transmission of electric length 90º to the central frequency of the GSM and DCS bands, respectively.
