3D-modeling of considering the design features of its manufacture in the HFSS package

The current level of industrial development, the widespread introduction of radio and telecommunications systems lead to a deterioration of the electromagnetic environment. The increased level of out-of-band radiation of radio transmitting devices for various purposes, industrial interference, interference from electronic countermeasures systems, as well as interference caused by various natural phenomena, leads to malfunctions of existing radio electronic equipment. Filters with a large (at least 60 dB) attenuation in the reject band must be used for protection Equipment from interference and solving the problem of electromagnetic compatibility. Such filters should not only effectively suppress interference in the required frequency range, but also have a good screening against penetration of external interference into the equipment.
