초록
A coupler is a microwave passive component used for power coupling or dividing. Regarding the trend of current telecommunication systems it is highly desirable for monolithic integration of passive components as such LTCC(Low temperature cofired ceramics) technology offers potential advantage in size, cost and performance. Utilizing LTCC technology a 2012 size type dual band coupler for DCS and EGSM band was fabricated. Its characteristics such as coupling, insertion loss, isolation and directivity was measured and compared with simulation results
