Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 70H33 is the minimum of the pass band attenuation amin. The minimum of the pass band
attenuation amin is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 20 dB
filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid for both the reference frequency fc 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.

values only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
