Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 152 is the maximmum pass band attenuation, which is is defined as
the insertion loss ae. The nominal frequency fN is fixed at 152,8 MHz without tolerance or limit. The values of relative
attenuation arel are guaranteed in the whole operating temperature range. The frequency shift of the filter in the operating
temperature range is included in the production tolerance scheme.
