Characteristics
Remark:
Reference level for the relative attenuation a of the TFS 460 C is the minimum of the pass band attenuation a
. The minimum of the pass band
min
rel
attenuation a
min
is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the
e o
3dB filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed on 460 MHz without tolerance. The given values for the
e
N
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 shifted
due to the temperature coefficient of frequency TC in the operating temperature range and due to a production tolerance for the centre frequency f
