Remark:
Reference level for the relative attenuation a
of the TFS 120 is the minimum of the pass band attenuation a . The minimum of the pass band
min
e c
rel
attenuation a
is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the
min
25 dB filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed on 120 MHz without tolerance. The given values for
e

the relative attenuation a
and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency f is
c
rel
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 .
