TFS70H38.doc version 1.1 11.09.01 VI TELEFILTER Measurement condition Ambient temperature: 23 C Input power level: 10 dBm Terminating impedances : for input: for output: 50 50 Filter Specification TFS 70H38 1/5 || 0 pF || 0 pF Remark: Reference level for the relative attenuation arel of the TFS 70H38 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 Tc f is valid for both the reference frequency f c and the frequency response of the filter on the operating temperature range.
