Annotation: The article proposes a new approach to modal filtration improvement, which is symmetrical adjunction of additional dielectric and conductor layers to the given structure. The article describes four-conductor reflection symmetric structure; amplitudes of decomposition pulses of this structure are equal and 8 times lower than EMF source amplitude. Besides, the length of a single segment of four-conductor structure is 1.2 times shorter than the total length of two-stage two-conductor structure, while output amplitudes are equal.
