Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 125K is the maximum attenuation in the pass band. The maximum attenuation in the
pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 125 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.
