Passive Filters: Basic Theory and Concepts

In contrast to active filters, in passive filters power transfer from the source to the load is very important. It is, therefore, not surprising that passive filter design is based on power related concepts and parameters. In this Chapter, the power transfer from the source to the load of the filter is presented in detail and all the necessary frequency dependent insertion (or effective) parameters are defined. The corresponding general passive filter design procedure is outlined which leads to the determination of the input impedance from the specified attenuation characteristics. The input impedance function is then synthesized using classical synthesis methods.
