Bandpass filter frequency F of microwave-band refers to the technique of high frequency and for selecting the microwave signal. Bandpass filter frequency F of microwave range, formed on the symmetrical line with distributed parameters on a substrate of a ceramic material with a low firing temperature. Technical result is a decrease in the size of 18 × 7 × 1 mm under stable values in the pass band under the effect of climatic factors, reducing the costs of setting at serial production. The filter comprises a dielectric substrate based on ceramic material with a low firing temperature, within which the elements formed on the symmetrical line with distributed parameters. On both sides of the substrate and end surfaces of the deposited metallized coating which shields the internal structure, which allows suppression of increase of bandwidth, and also minimizes the impact of external influences.
