Characteristics
Remark:
The maximum attenuation in the passband is defined as the insertion loss ae. The nominal frequency fN is fixed at 868.3 MHz without any tolerance or limit.
The values of absolute attenuation aabs 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.
