Design and implementation of reflectionless filters

Çubukcu, Ali İhsan
In this thesis, typical applications of absorptive filters are examined. To better understand the effect of out of band matching of RF and microwave filters on overall system, some experiment setupsare constructed and simulations are performed. In addition to this, three types of conventional absorptive filter topologies are analyzed and the realizability of each type is shown by explanation, simulation or measurement. Finally, a recently found method, reflectionless filter structures by Matthew Morgan, is analyzed and various types of reflectionless filters are designed and implemented. Furthermore, some approaches are stated to obtain better filter characteristics with the same topology.
