Experimental investigation of the characteristics of strip-band pass filters of the microwave with wide stop bands on a symmetric stripe line in the interests of ensuring electromagnetic compatibility

The method described in the article refers to the construction of bandpass filters (BPF) of ultrahigh frequencies (SHF) on inhomogeneous lines. This method allows you to choose the structure and parameters of the BPF in such a way as to achieve the maximum length of the stopband that meets the requirements of electromagnetic compatibility (EMC), with given restrictions on the attenuation characteristics in the passbands and stopbands, and also take into account design and technological restrictions on the difference in wave impedances and manufacturing permit. The article also presents the results of experimental studies of the characteristics of microwave bandpass filters with wide stopbands on a symmetrical stripline. These studies were carried out with the aim of ensuring electromagnetic compatibility.
