COURSE CONTENT

This course is devoted to the fundamentals of practical filter design for RF and microwave systems. Physical realizations suitable for both commercial and military applications will be presented. Several useful planar technologies will be discussed, including microstrip edge-coupled, hairpin, combline, and interdigital. At lower microwave frequencies, pseudo-lumped topologies using printed inductors and capacitors can be used to realize lowpass and bandpass filters. High Q filters using combline or dielectric resonator technology will also be presented. Both single channel filters and diplexers will be discussed. Various tuning procedures for filters will also be presented.

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 be presented, with examples and comments that relate specifically to filter design.
