Characteristics
Remark:
Reference level for the relative attenuation arel 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 on 622,105 MHz.
The data values given below are only valid for room temperature.
