2. Characteristics :
Remark: Reference level for the relative attenuation arel of the TFS70Y 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 reference frequency fc is the arithmetic mean value of the upper and lower
frequencies at the 3 dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid both for 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.

*) The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as
reference values only. Should there be additional questions, do not hesitate to ask for an application note or contact our design team.
