2. Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 130A
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 frequence
fc
is the arithmetic mean value of the upper and lower frequencies at the
1 dB
filter attenuation level relative to the insertion loss
ae
. The nominal
frequency
fN
is fixed on
130,38 MHz
without tolerance. The given values
for the relative attenuation
arel
and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency
fo
is
shifted due to the temperature coefficient of frequency
TCf
in the operating temperature range and due to a production tolerance for the centre
frequency
fc
.
