TFS 238a.doc version 1.1 VI TELEFILTER Preliminary Specification 10.04.2003 TFS 238 A 1/5 Measurement condition Ambient temperature TA: Input power level: Terminating impedances at fc*: 25 °C 0 dBm input: 1000 output: 670 // - 7,2 pF // - 7,8 pF Characteristics Remark: Reference level for the relative attenuation arel of the TFS 238A is the insertion loss. The minimum of the pass band attenuation amin is defined as the insertion loss ae . 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 in the operating temperature range.
