Filters are one of the fundamental building blocks of RF and microwave systems, along with amplifiers, oscillators, mixers, and switches. Filter design and realization can be challenging for several reasons. No one technology or filter topology is suitable for all applications. There is also a fundamental limitation imposed by the relationship between unloaded Q and volume. Many of the simpler design procedures can sometimes arrive at geometries that are unrealizable, and the available literature is generally focused on theory rather than practical information on realization. However, with a few basic concepts in hand, even the non-specialist can achieve useful results.
EM simulation is also an essential component of modern filter design. We now have the ability to model and optimize complete filter structures in the EM domain. Current developments in cluster computing and multi-threading promise to enhance those capabilities as well.
Learning Objectives:
Upon completing the course, the participant will be able to:- use a universal procedure for narrow band filter design that can be applied to virtually any filter technology or topology
- understand fundamentals of practical filter design for RF and microwave systems
- apply Dishal’s method - with powerful extensions that include the port tuning concept, equal ripple optimization techniques, and efficient EM simulation
- extract data from hardware and from EM simulations
- extract unloaded Q, external Q, and coupling coefficients during the design process and in evaluating prototypes
Target Audience:
The course material is suitable for filter designers, designers of other components, systems engineers, and technical managers.
