Characteristics
Remark: Reference level for the relative attenuation arel of the TFS 315 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 fo is the arithmetic mean value of the upper and lower
frequencies at the 15 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 315 MHz without tolerance. The
given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below also if the centre
frequency fo 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 fo.
