Characteristics
Remark:
The maximum of the pass band attenuation amax is defined as the insertion loss ae. The nominal frequency f
is fixed at 869,0 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 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.
