Design Process of Cavity-Based, Helical Resonator Filters Enters Higher Ground (.PDF Download)

The performance of a cavity-based filter is determined by its geometry. Although these filter structures can be tuned, it can be a challenge to obtain the proper geometric dimensions that allow the tuning elements to attain the desired synthesized response. Simulation software is a valuable tool that can assist with the design of such filters. In the application note, “Cavity
