Remark:
The reference level for the relative attenuation a of the TFS 110K2 is the minimum of the pass band attenuation. This value is defined as the insertion
rel
loss a . The nominal frequency f is fixed at 110.6 MHz without any tolerance. The values of relative attenuation a
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.
