Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 36A
is the minimum of the pass band attenuation
amin
. 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
40 dB
filter attenuation level relative to the insertion loss
ae
. The nominal frequency
fN
is fixed on
36 MHz
without tolerance. The temperature
coefficient of frequency
Tc
is valid both for the reference frequency
fc
and the frequency response of the filter in the operating temperature range. The
frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
