Characteristics
Remark:
The maximum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 1003 MHz without any tolerance or
limit. Reference level for the relative attenuation arel of the TFS 1003 is the insertion loss ae. The values of absolute attenuation aabs 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.
