Design of an Evanescent Mode Circular Waveguide 10 GHz Filter

Ham radio operation at 10 GHz is far removed from global shortwave communication typically operating below 30 MHz. The motivation for designing the evanescent mode circular waveguide 10 GHz filter sprang from a desire to extend ham radio operation to 10 GHz.  This application note describes the design of two 10 GHz filters and is a follow up to a previous article published in Microwave Product Digest describing the design of a 10 GHz low-noise amplifier (LNA). Both are key components needed for ham radio station operation at 10 GHz.
