Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 156B is the maximum of the pass band attenuation. This value is defined as the insertion
loss ae. The nominal frequency fN is fixed at 156,65 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.
