A Study on Optimum Broadband Design Including of CATV Transmitting Circuits

The broadband Power Splitters and Tap-Offs are needed to transmit a number of channels of signals with the high quality 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 Wilkinson'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.
