Characteristics
Remark:
Reference level for the relative attenuation a rel of the TFS 208B is the maximum attenuation in the passband. The maximum attenuation in the pass
band is defined as the insertion loss a e . The nominal frequency
a rel 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.
