DW9274 DW9274 92.025MHz IF SAW Filter GND 3 GND 4 INPUT Reference level for the relative attenuation arel of the DW9274 is the insertion loss. The insertion loss ae is defined as the insertion loss at the nominal frequency fN. The centre frequency fC is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf 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.
