Characteristics
Remark:
The nominal frequency fN is fixed at 299 MHz. The insertion loss ae is defined as loss value determined at fN. Reference level for the relative attenuation
arel of the TFS 299 is the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 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.
**) ∆fc(Hz) = TCf(ppm/K2) x (T-T0)2 x fTo (MHz).
