Input power level:
Terminating impedances at fc *) :
2. Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 70AA
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
3 dB
filter attenuation level relative to the insertion loss
ae
. The nominal frequency
fN
is fixed at
70 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 even if the
centre frequency
fc
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
.

*) The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as
reference values only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
