Characteristics
Remark: Reference level for the relative attenuation arel of the TFS 144 is the minimum of the pass band attenuation amin. It is defined as the insertion loss ae. The centre frequence fc is the arithmetic mean value of the upper and lower frequencies at the 1,5 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 144 MHz without tolerance. The given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency fc 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. **) fc(Hz) = Tcf(ppm/K) x (To - TA) x fTo (MHz) fTo is reference frequence fc at frequency inversion temperature (To)
