Characteristics
Remark:
The reference level for the absolute attenuation
aabs of the TFS 400L is the attenuation at nominal frequency. This value is defined as the insertion loss
ae. The nominal frequency fN is fixed at 400,0 MHz without any tolerance. The values of the 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.
