Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 177B is the maximum attenuation in the pass band. The maximum attenuation in the pass
band is defined as the insertion loss ae. The nominal frequency f_N is fixed at 177,0 MHz without any tolerance or limit. The values of relative attenuation
arel are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range 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.
**) ∆f(Hz) = TCf(ppm/K) x (T-T₀) x fcat(MHz).
