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 30 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 285 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 ______________________________________________________________________________________________________ 9,5 dB max. 12 dB ae = amin Insertion loss (Reference level) ______________________________________________________________________________________________________ 285 MHz fN Nominal frequency _____________________________________________________________________________________________________ Pass band Pass band ripple fN 7,5 MHz 0,8 dB max. 1,2 dB Passband width 3 dB min. 20 MHz ______________________________________________________________________________________________________ Group delay GD Group delay ripple fN 7,5 MHz 90 ns max. 150 ns ______________________________________________________________________________________________________ Relative attenuation arel typ. value tolerance / limit fN 75 MHz ... fN - 20 MHz 38 dB min. 30 dB fN + 20 MHz ... fN + 75 MHz 38 dB min. 30 dB ______________________________________________________________________________________________________ VSWR ratio max. 2:1 at fN - 7,5 MHz ... fN + 7,5 MHz ______________________________________________________________________________________________________ Operating temperature range - 5 C ... + 85 C ______________________________________________________________________________________________________ - 72 ppm/K Temperature coefficient of frequency TCf ______________________________________________________________________________________________________ Input power level max. + 10 dBm ______________________________________________________________________________________________________ Generated: Checked / approved: ______________________________________________________________________________________________________ VI TELEFILTER Vectron International, Inc.
