2. Characteristics
Remark:
Reference level for the relative attenuation a of the TFS 100C is the minimum of the pass band attenuation a
. The minimum of the pass band
is defined as the insertion loss a . The reference frequency f is the arithmetic mean value of the upper and lower frequencies at
rel min
attenuation a
min
e
c
the 3 dB filter attenuation level relative to the insertion loss a . The temperature coefficient of frequency Tcf is valid both for the reference frequency
e
f
and the frequency response of the filter in the operating temperature range. The bandwidth shift of the filter in the operating temperature
c
range (OTR) is included in the production tolerance scheme.
