DW9274
DW9274
92.025MHz IF SAW Filter
Replaces July 2002 version, DS4082-2.1
DS4082-3.0 December 2003
Reference level for the relative attenuation a
rel
of the DW9274
is the insertion loss. The insertion loss ae is defined as the
insertion loss at the nominal frequency f
N
. The centre frequency
f
C
is the arithmetic mean value of the upper and lower
frequencies at the 3 dB filter attenuation level relative to the
insertion loss a
e
. The temperature coefficient of frequency T
cf
is
valid both for the reference frequency f
C
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.
