Characteristics
Remark:
The maximum of the pass band attenuation amax is defined as the insertion loss ae. The nominal frequency fN is fixed at 315,0 MHz without
tolerance. The given values for the absoult attenuation arel have to be reached at the frequencies given below even if the filter charactristic is
shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance..
