Remark:
Reference level for the relative attenuation a
of the TFS173A is the minimum of the pass band attenuation a . The minimum of the pass
min
rel
band attenuation a
is defined as the insertion loss a . The reference frequency f is the arithmetic mean value of the upper ( f3dB+ ) and lower
min
e c
(f3dB-) frequencies at the 3 dB filter attenuation level relative to the insertion loss a . The temperature coefficient of frequency Tcf is valid both
e
for the reference frequency f and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the
c
operating temperature range is not included in the production tolerance scheme.

For final test we use scheme 1 ( with variable coils L1 and L2.)
Influence of inductors L1 and L2 on filter slope is stronger , as of L3 and L4 ( please, refer to Application
Note ).
For this reason, it is possible to match the filter to minimum slope changing L3 and L4 using fixed E12
series inductor values ( SMD-elements ) for L1 to L4 .
If you use variable coils, then it is better to use scheme 1 with variable coils L1 and L2 ,
