Cavity-Based Helical Resonator Bandpass Filters Designed With Parameterized Project Template in NI AWR Software

EL SEGUNDO, Calif. – Jan. 12, 2016 --  A new NI AWR Design Environment™ application note describes a novel design process for a family of ultra high-frequency (UHF) cavity-based helical resonator bandpass filters. Leveraging a parameterized project template, the entire process of designing for a new filter frequency could be accomplished in less than a day. First pass success was achieved on three different frequency filter designs. Microwave Office circuit design software was used to create a complete "synthesis to implementation" process for the entire filter design, including the generation of fabrication files. A hierarchical modeling approach was used for the cavities that included optimization of the circuit model in Microwave Office and verification using Analyst™ electromagnetic (EM) simulation.
