The article provides a comparative analysis of electrodynamic methods implemented in modern microwave CAD systems. A qualitative assessment to modeling methods in solving various design problems is given. An example of circuitry and electrodynamic modeling methods usage when developing X-band band-pass filter is considered. The aim of the work is to solve by electrodynamic and analytical methods the problem of expanding stopband of a band-pass filter on Hairpin resonators by compensating spurious pass-bands. The technology of X-band band-pass filter research based on modern methods of circuitry and electrodynamic modeling is presented.
Key words: electrodynamic and circuit methods, microwave CAD, modeling, microwave devices, bandpass filter with extended stopband.
