Characteristics
Remark:
The nominal frequency fN is fixed at 153,6. The insertion loss ae is defined as loss value determined at fN. Reference level for the relative attenuation arel
of the TFS153C is the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter
attenuation level relative to the insertion loss ae. All specified data are met within the operating temperature range.

*) 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.
