Real frequency design of narrowband impedance equalizer with complex terminations
in this thesis the real frequency design of L Pi and T type networks with complex terminations has been analyzed. The main purpose of the proposed approach is to compare the existing methods against the proposed method on impedance matching design in narrowband with complex termination. There are two types of models the serial model for T type network design and the parallel model for Pi and L type networks design. The generator and load termination impedances are given as measured values. Thus they can be considered as a resistance and a reactive element connected in series. To be able to design a Pi type narrowband matching network these series impedance models must be transformed into parallel models. But for T type network designs the assumed serial models can be used there is no need for a transformation process. Then the corresponding Pi or T type networks can be designed by using Q based method that is well-defined in the literature. The proposed approach is a new method for designing narrowband impedance matching networks. The purpose of this new method is to configure impedance matching networks for all types L Pi and T without the need for termination models with component values. For comparison with existing methods the complex terminations part and the Q based method equations have been derived and a new Q based method (modified) is considered for the new method. The proposed approach is illustrated by different examples of network types L Pi and T.
