Characteristics

Remark:

The reference level for the relative attenuation arel of the TFS 84 is the minimum of the pass band attenuation. This value is defined as the insertion loss

ae. The nominal frequency fN is fixed at 84,375 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.
