Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 60A is the insertion loss. 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 temperature coefficient of frequency Tc
f
is valid both for the reference frequency fc and the frequency
response of the filter in the operating temperature range
.
