Characteristics
Remark:
The reference level for the relative attenuation a rel of TFS374D is the minimum of the pass band attenuation a min. This value is defined as the insertion loss ae . The centre 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 a e. The given values for the relative attenuation a rel and the group delay ripple have to be reached at the frequencies given below, even if the centre frequency f c is shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the centre frequency fc.

*) 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. **) f(Hz) = TCf(ppm/K) x (T-T0) x fTo(MHz)
