Remark:

Reference level for the relative attenuation arel of the TFS 45 A is the minimum of the pass band attenuation amin. The minimum of the pass and

attenuation amin is defined as the insertion loss ae. The centre frequency fo is the arithmetic mean value of the upper and lower frequencies at the

3dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency

is valid both for the reference frequency

and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating temperature range is

not included in the production tolerance scheme.
