Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS135E is the minimum of the pass band attenuation. This value is defined as the insertion loss
ae. The nominal frequency fN is fixed at 135,53 MHz without any tolerance. The frequency shift of the filter in the operating temperature range is not included
in the production tolerance scheme. But values of relative attenuation are guardbanded to compensate for the difference of frequency shift over temperature
at the limits of the operating temperature range between a device with typical frequency inversion temperature and devices at the limits of frequency inversion
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/K²) x (T-T0)² x fTo(MHz).
