| version 1.1 06.01.02 ______________________________________________________________________________________________________ TFS471.doc VI TELEFILTER Filter Specification TFS 471 1/3 ______________________________________________________________________________________________________ Measurement condition Ambient temperature: Input power level: Terminating impedance: 23 C 0 dBm 310 || -1,1 pF Construction and pin connection see page 2 50 test circuit see page 2 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 471 is the maximum of the pass band attenuation amax. The maximum of the attenuation within the usable signal bandwidth 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 471,55 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 ______________________________________________________________________________________________________ 3,5 dB max. 5 dB ae = amax Insertion loss (Reference level) ______________________________________________________________________________________________________ fN Nominal frequency 471,55 MHz ______________________________________________________________________________________________________ f0 Centre frequency 471,55 MHz ______________________________________________________________________________________________________ typ. value Variation/ Limitation 280 kHz BW 3 dB - bandwidth ______________________________________________________________________________________________________ Usable signal bandwidth min. fN 10 kHz ______________________________________________________________________________________________________ Relative attenuation arel fN + 910 kHz min. 52 dB ______________________________________________________________________________________________________ -0,036 ppm/K2 TCf Temperature coefficient of frequency ______________________________________________________________________________________________________ Frequency inversion temperature + 25 C ______________________________________________________________________________________________________ Operating temperature range - 20C ... + 70C ______________________________________________________________________________________________________ Generated: Checked / approved: ______________________________________________________________________________________________________ VI TELEFILTER Vectron International, Inc.
