Characteristics :
Remark:
Reference level for the relative attenuation
arel
of the
TFS 44E
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
20 dB
filter attenuation level relative to the insertion loss
ae
. The nominal frequency
fN
is fixed at
44 MHz
without tolerance.
The temperature coefficient of frequency
Tc
f
is valid both for the reference frequency
fc
and the frequency response of the filter. All specified
parameters have to be reached in the operating temperature range (
OTR
) .
