Description Specifications Electrolink DAB BIII Band Pass Filter Electrolink has expanded its radio filter products to include DAB fi lters. Electrolink is providing filters with up to 8 cavities to meet the strict requirements of both the critical and non-critical masks. All the filters are fully compliant with the Eureka 147 international specification achieved at DAB (170 – 240 MHz) and L Band (1452 -1492 MHz) frequencies at powers ranging from 200 W to 3 kW. All Electrolink fi lters are DAB band tunable and temperature compensated. The bandpass filters use light alloy and brass construction for stable high power performance.
