terminating impedances
Characteristics
Remark:
Reference level for the relative attenuation a rel of the TFS211C is the minimum of the pass band attenuation a min . The minimum of the pass band
attenuation a min is defined as the insertion loss a e . The centre frequency f c is the arithmetic mean value of the upper and lower frequencies at the 1
dB filter attenuation level relative to the insertion loss a e . The given values for the relative attenuation a rel and for the group delay ripple have to be
reached at the frequencies given below also if the centre frequency f c is shifted due to the temperature coefficient of frequency TC f in the operating
temperature range and due to a production tolerance for the centre frequency f c .

Note 1) - f (Hz) = TC (ppm/K²) x (T - To)² x F
Note 2) If the filter is used between -10°C and -35°C all given frequencies may be changed down to max. - 30 kHz
