Abstract

Nowadays, the study on the ceramic components and modules used in telecommunication system is being performed. Coupler is a microwave passive component used for power coupling or dividing and directional coupler is designed to be possible optional dividing percentage. In our research, We developed 14dB and 19dB directional couplers of DCS band. The good characteristics, the target insertion loss and high isolation, of couplers is obtained by LTCC processing using a ceramic material.
