CEI: Cavity Filters and Multiplexers for Wireless Applications

Sep 27, 2017 to Sep 29, 2017
Event location: 
Amersfoort, The Netherlands

This course is focused on practical filter design methods for cavity combline filters for wireless systems. The core material is a universal procedure for narrow band filter design that can be applied to virtually any filter technology or topology. The procedure is rooted in Dishal's method with powerful extensions that include the port tuning concept, equal ripple optimization techniques, and efficient EM simulation. All the techniques presented can be implemented using commercially available CAD tools.

Practical procedures for extracting unloaded Q, external Q, and coupling coefficients are quite important in the design process and in evaluating prototypes. These techniques will include extracting data from hardware and from EM simulations. Some tutorial material on field-solvers will also be presented. The EM simulation examples relate specifically to cavity filter design and include tips and techniques for more accurate and efficient simulation.

Example filter designs will be presented with measured data and error analysis. The instructor will choose examples to develop based on the interests of the class. The course material is suitable for filter designers, designers of other components, systems engineers, and technical managers.
