Reference level for the relative attenuation a rel 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 nominal frequency f N is fixed to 210,38 MHz. The given values for the relative attenuation a rel and for the
phase 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 .
