Characteristics
Remark:
Reference level for the relative attenuation arel is the pass band attenuation at the nominal frequency fN. It is defined as the insertion loss ae. The
nominal frequency fN is fixed to 286,00 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.
