A systematic way to YIG-filter-design

M. Aigle; Gerd Hechtfischer; Wilhelm Hohenester; Ralf Jünemann; Christian Evers

YIG-filters are key components in microwave test and measurement instruments. Whereas their basic principles are well established, only few details about the design and realization of modern multi-octave filters have been published. Therefore, research and development to find a systematic and accurate way of calculating and reproducibly building modern YIG-filters has been initiated at Rohde & Schwarz. This enables us to obtain a profound understanding and control of parameters and overcome empirical methods of manual rework.
