Characteristics
Remark:Reference level for the relativeattenuation arel of the TFS 70ACis the minimum of the pass band attenuation amin. The minimum of the pass band attenuation aminis defined as the insertion loss ae The centre frequency fc is the arithmetic mean value of the upper and lower frequenciesat the 3dB filterattenuationlevel relativeto the insertion loss ae . The temperature coefficient of frequency Tc fisvalid for both thereference frequency fc and the frequency response of the filter in theoperating temperature range.
