Characteristics
Remark:
Reference level for the relative attenuation arel is the pass band attenuation a0 at nominal frequency. It is defined as the insertion loss ae. The
nominal frequency fN is fixed to 190,0 MHz. The given values for the insertion loss, the relative attenuation arel and the group delay ripple have to
be reached at the frequencies given below also 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.
