Description Specifications COM-TECH DAB Band Filter Solid state transmitters produce frequency emissions that must be removed by band-pass filters. COM-TECH band pass filters are designed to meet all transmission masks (DVB-T / DVB-T2, ATSC 1.0 / ATSC 3.0, ISDB-T, DAB, etc.). They are also the main components of the Combiners: The COM-TECH band-pass filters are specially made for use in the DAB band 174-240 Mhz and suitable for local/regional use of DAB in the Netherlands. COM-TECH bandpass filters are designed, developed and manufactured with the very latest technology to ensure the maximum reliability and the most advanced performance: highest voltage safety margins, lowest insertion loss, maximum compactness, exceptional mechanical stability and durability.
