Abstract. This paper presents the results of the research  and development of the narrow band STW filters with a fractional bandwidth of 0.07-0.12 %. Use of the asynchronous topology, constructional, topological and technological optimization with a computer simulation by an equivalent circuit model on the base P-matrix method with the LC- matching  allowed reduce the insertion loss of the filters down to 2.0-2.2 dB in a extended frequency range of 500-1344 MHz.

Key words: surface transverse waves, filter, insertion loss.

Financing: The work was carried out according to the state task of the Omsk Scientific Center SB RAS (project registration number 124022500291-6)
