Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 868 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_N is fixed on 868,39 MHz without tolerance. The given
values for the relative attenuation arel have to be reached at the frequencies given below also if the centre frequency f_c is shifted due to the
temperature coefficient of frequency TC _f in the operating temperature range and due to a production tolerance for the centre frequency f_c. The
values in brackets are to be guaranteed at ambient temperature (23 °C).
