Characteristics

Remark:

The reference level for the relative attenuation arel of the TFS134D is the minimum of the pass band attenuation. This value is defined

as the insertion loss ae. The nominal frequency fN is fixed at 134,0 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.
