  • Design table formation of stepped impedance prototype filters 

    Authors:Şengül, Metin Y.
    Publisher and Date:(Istanbul University, 2010)
    In literature there exist some tables containing normalized element values to design low-pass lumped-element prototype filters with several different responses like maximally flat or equal-ripple. In this work an algorithm is presented to form such tables for stepped impedance prototype filters. By using the proposed algorithm a table for 0.5 dB equal-ripple stepped impedance prototype filter is formed. Then a design example is given to show the utilization of the formed table.

  • Phase Shifting Properties of High-Pass and Low-Pass Mixed-Element Two-Ports 

    n many applications, circuits containing lumped-elements are preferred because of their small sizes. But it is not possible to avoid losses caused by the connections between lumped-elements at high frequencies. However, the use of these connections as circuit elements will improve the performance of the circuit. Therefore, it becomes inevitable to use circuits with mixed (lumped and distributed) elements at high frequencies. In this brief, phase shifting properties of high-pass and low-pass ...
