2. Characteristics
Remark:
Reference level for the relative attenuation a
of the TFS 100 A is the minimum of the pass band attenuation a
. The minimum of the pass
rel
min
band attenuation a
is defined as the insertion loss a . The reference frequence f is the arithmetic mean value of the upper and lower
min
e c
frequencies at the 33 dB filter attenuation level relative to the insertion loss a . The temperature coefficient of frequency Tcf is valid both for the
e
reference frequency f and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating
c
temperature range is not included in the production tolerance scheme.
