2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 120A is the insertion loss. The insertion loss ae is defined as the insertion loss at the nominal
frequency fN . 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 ae. The temperature coefficient of frequency Tcf is valid for both the reference frequency fc and the frequency response of the filter on the
operating temperature.

*) 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)² x fTo(MHz).
