Terminating impedances *:
Remark:
Reference level for the relative attenuation
arel
of the
TFS 70H21
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 reference frequency
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 temperature coefficient of frequency
Tc
f
is valid both for the
reference frequency
fc
and the frequency response of the filter at the operating temperature. The frequency shift of the filter at the operating
temperature not included in the production tolerance scheme.

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.
