Characteristics
Remark:
The maximum of the pass band attenuation amax is defined as the insertion loss ae. The nominal frequency f_N is fixed at 868,3 MHz without tolerance.
The given values for the absolute attenuation ae have to be reached at the frequencies given below even if the centre frequency fN 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 fN.
