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 nominal frequency fN is fixed to 210,38 MHz. The given values for the relative attenuation arel and for the
phase ripple have to be reached at the frequencies given below also if the centre frequency fo 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 fo.
