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_relof the DW9274

is the insertion loss. The insertion loss a is defined as the

insertion loss at the nominal frequency f_N. The centre frequency

f_Cis 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_cfis

valid both for the reference frequency f_Cand 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.
