Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 199L is the minimum of the pass band attenuation amin. The minimum of the pass band
attenuation amin is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 1 dB
filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed at 199.68 MHz without any tolerance. The given values for both the
relative attenuation arel and the group delay ripple have to be achieved at the frequencies given below even if the centre frequency fc is shifted due to the
temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the centre frequency fc.

*) 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.
**) Applies over any 3.84MHz within pass band
***) Measured with tones spaced at 5 MHz and 15 MHz above and below f_N
****) This power level is allowed for short term operation (10% of life time) only, the max. input power for continuous operation is 10 dBm.
*****) ∆fc(Hz) = TC_f(ppm/K) x (T - T_o) x f_To (MHz).
