Remark:

The reference level for the relative attenuation a of the TFS 125C is the maximum attenuation in the pass band. The maximum attenuation in the pass

rel

band is defined as the insertion loss a . The nominal frequency f_Nis fixed at 125,0 MHz without any tolerance or limit. The values of relative attenuation

are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the

rel

production tolerance scheme.
