Characteristics
Remark:
The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fC is the frequency of the minimum of the
passband attenuation a_min. The tolerance for the centre frequency also includes a frequency shift due to the temperature coefficient of frequency TCf in the
operating temperature range and 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.
**) ∆f(Hz) = TCf(ppm/K²) x (T₀-T)² x f_CAT(MHz).
