Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 346A
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 temperature coefficient of frequency Tc
f
is valid for both the
reference frequency fc and the frequency response of the filter in the operating temperature range
.

*) 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.
