Characteristics
Remark:
The reference level for the relative attenuation arel of TFS 133C is the minimum of the pass band attenuation amin. 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 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 variation of the filter band width in the operating temperature range (OTR) is 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.
**) The attenuation of coupling coil resonance can be down to 40 dB. The exact position will be defined.
***) 2 narrow band distortions below 35 dB are acceptable.
****) ∆f(Hz) = TCf(ppm/K²) x (T-T0)² x fTo(MHz)
