Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 1485 is the maximum attenuation in the passband 1. The maximum attenuation in the pass
band
1
is
defined
as
the
insertion
loss
ae.
The
nominal
frequency
fNB
B
is
fixed
at
1485
MHz
without
any
tolerance
or
limit.
The
values
of
relative attenuation
arel are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the
production tolerance scheme.
