TFS116

Tfs116.doc version 1.3 29.05.2001 VI TELEFILTER Measurement condition Filter Specification TFS 116 1/5 Ambient temperature: 23 °C Input power level: 0 dBm Terminating impedances for input: 740 Ohm // -4,0 pF for output: 740 Ohm // -4,0 pF External coil: 290 nH Characteristics Remark: Reference level for the relative attenuation arel of the TFS 116 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 116.6 MHz without tolerance. The specified values have to be reached in operating temperature range.
