Carried out an approximate calculation of the band-pass filter symmetric coplanar line and experimental study of the layout of the designed filter for the purpose of comparison of theoretical and experimental results. Experimentally studied the layout of the tunable bandpass filter whose operating frequency without current in the windings of small magnetic systems was 7380 MHz. The range of adjustment of the layout of the filter when you change the voltage on the windings from -1,2 V to +1.2 V is 6960-7620 MHz, and its width is 560 MHz.
