| version 1.2 06.01.02 ______________________________________________________________________________________________________ TFS80A.doc VI TELEFILTER Filter specification TFS 80 A - Page 1 / 3 ______________________________________________________________________________________________________ Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Termination impedance: Input: 110 || - 18 pF Output: 50 || - 13 pF Characteristics Remark: Reference level for the relative attenuation arel of the TFS 80 A is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fo is the arithmetic mean value of the upper and lower frequencies at the 3dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 80,0 MHz without tolerance. The given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency fo is shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the centre frequency fo Data ______________________________________________________________________________________________________ max. 16,5 dB ae Insertion loss (Reference level) ______________________________________________________________________________________________________ 80,0 MHz fN Nominal frequency ______________________________________________________________________________________________________ Pass band fN - 100 kHz ... fN + 100 kHz ______________________________________________________________________________________________________ Relative attenuation arel typ. value tolerance / limit fN 100 kHz ... fN + 100 kHz max 1 dB fN 500 kHz min 35 dB fN 600 kHz min 40 dB fN 700 kHz min 45 dB fN 1000 kHz min 50 dB fN 5000 kHz ... fN 25 MHz min 55 dB ______________________________________________________________________________________________________ GD Group delay Absolute delay fN - 100 kHz ... fN + 100 kHz 4,55 s max 4,85 s Ripple fN - 100 kHz ... fN + 100 kHz max 600 ns ______________________________________________________________________________________________________ Z Impedance Source impedance 110 // - 18 pF Load impedance 280 // - 13 pF ______________________________________________________________________________________________________ - 0,045 ppm/K TCf *) Temperature coefficient of frequency ______________________________________________________________________________________________________ 23 C Frequency inversion temperature To ______________________________________________________________________________________________________ Operating temperature range - 20 C ... + 85 C Storage temperature range - 40 C ... + 85 C ______________________________________________________________________________________________________ 12 V Permissible DC voltage VDC 10 V Permissible AC voltage Vpp ______________________________________________________________________________________________________ *) f(Hz) = TCf(ppm/K) x (T) x fTo(MHz) Generated: Checked / approved: ______________________________________________________________________________________________________ VI TELEFILTER Vectron International, Inc.
