The reference level for the relative attenuation arel of the 75C is the minimum of the pass band attenuation amin. The attenuation at fN is defined as the
insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 1,5 dB filter attenuation level relative to the
insertion loss ae. The nominal frequency fN is fixed at 75 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.
