A Study on Optimum Broadband Design Including of CATV Transmitting Circuits.

CATV전송회로의 최적.광대역 설계 및 제작에 관한 연구

The broadband Power Splitters and Tap-Offs are needed to transmit a number of channels of signals with the high quality of signals. In this paper the design theories and analysis of the theoretical frequency characteristics of the Wilkinson's Power Splitters and Tap-Offs are reviewed. Then it has been showned that the theoretical frequency characteristics of the proposed compensated Wilkinson's Power Splitter and Tap-Off are improved much in comparison with the prototype wikinson's Power Splitter and conventional weakely-coupled Tap-Off. Furthermore the measured results of frequency characteristics for the fabricated circuits show agreement with the theoretical results and hence the validity of the proposed design and analysis methods has been confirmed.
