Tfs119.doc version 1.4 28.06.2000 ______________________________________________________________________________________________________ VI TELEFILTER Filter Specification TFS 119 1/5 ______________________________________________________________________________________________________ Measurement condition Ambient temperature: 23 °C Input power level: 0 dBm Terminating impedances for input: 1 kOhm // -1,5 pF for output: 1 kOhm // -1,5 pF Characteristics Remark: Reference level for the relative attenuation arel of the TFS 119 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 nominal frequency fN is fixed on 119.6 MHz without tolerance. The specified values have to be reached in operating temperature range.
