Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 915F is the minimum attenuation in the pass band. The minimum attenuation in the pass
band is defined as the insertion loss ae. The nominal frequency f_N is fixed at 915 MHz without any tolerance or limit. The frequency shift of the filter in the
operating temperature range is included in the production tolerance scheme.
