Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 868B is the minimum of the pass band attenuation amin. The minimum of the pass
band attenuation amin is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies
at the 3 dB filter attenuation level relative to the insertion loss ae. The nominal frequency f
is fixed at 868,35 MHz without tolerance. The given
values for the relative attenuation arel have to be reached at the frequencies given below even if the centre frequency f
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 f
