Characteristics

Remark:

Reference level for the relative attenuation a rel of the TFS 282 A1 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 282 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 .
