2. Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 120C
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 nominal frequence
f
N
is fixed at
120,0 MHz
without tolerance or limit.
The reference frequence
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 temperature coefficient of frequency
Tc
f
is valid both for the reference frequency
fc
and the frequency response of the
filter in the operating temperature range.
