Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS869L is the maximum of the passband attenuation amax. The maximum of the passband
attenuation amax is defined as the insertion loss ae. The nominal frequency fN is fixed at 869.2125 MHz without any tolerance. The values of the relative
attenuation arel are guaranteed over the whole operating temperature range. The frequency shift of the filter within 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.
**) power durability requirement is 10 dBm for each 4 seconds per hour over lifetime
