2. Characteristics :
Remark:
Reference level for the relative attenuation a
of the TFS 70H26 is the minimum of the pass band attenuation a . The minimum of the pass
min
rel
band attenuation a
is defined as the insertion loss a . The reference frequency f is the arithmetic mean value of the upper and lower
e c
min
frequencies at the 3 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
c
operating temperature range is not included in the production tolerance scheme.
