Abstract :
Many authors have published methods to synthesize microwave filters that provide a circuit prototype composed of ideal resonators and ideal couplings between them. Usually, the implementation step of that network with a particular technology is provided with few details. This work presents a method to synthesize a rectangular waveguide filter with transmission zeros designed by the extracted pole method, focusing on the modelling and implementation of the non-resonant nodes by means of detuned cavities.
