Remark:
Reference level for the relative attenuation arel of the TFS 340 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 f
is the arithmetic mean value of the upper and lower frequencies at
the 3dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed at 340,0 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 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
