FIELD: electricity.
SUBSTANCE: multilayer bandpass filter comprises parallel dielectric layers of the resonance thickness, each separated from one another and from the surrounding space by a flat grid of parallel thin film strip conductors with ordered axes. The axes of any two adjacent grids are orthogonal.
EFFECT: improved selective properties of the filter, expressed in the extension of the upper boom band due to the significant increase in the frequency of the second oscillations mode of dual-layer resonators compared to the frequency of the first oscillations mode.
