This value is defined as the insertion loss ae. The nominal frequency fN is fixed at 245.76 MHz without any tolerance. The values of relative attenuation arel are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
