Characteristics
Remark:
The minimum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency f_N is fixed at 810 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.
