A Study on the Power Divider for CATV/DBS/ Systems
CATV/DBS 시스템용 차세대 분배기에 관한 연구
Abstract
In this paper, we have dealt with the design and analysis methods of the frequency charateristics for the power dividers which are extensively used in CATV and DBS(Direct Broadcasting Satellite) systems. The lumped-element circuits have been implemented based on the Wilkinson power divider and the charateristics of the circuits approximated to ideal transformer examined. Then the frequency characteristics are analysised by using even - odd-mode method. Furthermore, in order to improve the charateristics, the optimum design method by adding compensating circuit has been Proposed and it has been shown that the charateristics are improved remarkably.
