-2000 SURFACE ACOUSTIC WAVE FILTER FOR IMT-2000 SYSTEM

摘要

The present invention relates to a SAW filter for the IMT-2000 system that filters the wideband signal for the IMT-2000 is mounted in a SAW filter, in particular a terminal for the IMT-2000 system for system IMT-2000 as their desired band, the present invention According to the SAW filters by IMT-2000 system, causing production to producers due to convenience because now so you can build a broadband SAW filter using 1.25㎒ narrow-band SAW filter for CDMA systems that are listed in the existing prototype, the materials purchased not only provide speed and fabrication ease in the process of time, to relieve Despite the current problems of the song for because of the untapped existing broadband SAW filter IMT-2000 terminals have been caused / receiver by giving unspecified large number of people to the IMT-2000 there is an excellent effect that it can provide a terminal for.
