Characteristics
Remark:
Reference level for the relative attenuation a rel of the TFS 244 B 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 o is the arithmetic mean value of the upper and lower frequencies at the 3
dB filter attenuation level relative to the insertion loss a e . The nominal frequency f N is fixed on 244 MHz without tolerance. 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 o 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 o .
