| file: TFS460C.doc version 1.2 06.01.02 ______________________________________________________________________________________________________ VI TELEFILTER Filter specification TFS 460 C 1/3 ______________________________________________________________________________________________________ Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Source impedance: 184 || -0.33 pF Load impedance: 184 || -0.33 pF Construction and pin connection (see page 2) Characteristics Remark: Reference level for the relative attenuation arel of the TFS 460 C 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 460 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 dB max 5 dB ae = amin Insertion loss (Reference level) ______________________________________________________________________________________________________ 460 MHz fN Nominal frequency ______________________________________________________________________________________________________ 460 MHz Centre frequency fo ______________________________________________________________________________________________________ Pass band ripple fN 10 MHz 1 dB max. 2 dB ______________________________________________________________________________________________________ Relative attenuation arel typ. value tolerance / limit 360 MHz ... 380 MHz 60 dB min. 50 dB 405 MHz ... 425 MHz > 40 dB min. 40 dB ______________________________________________________________________________________________________ Operating temperature range - 25 C ... + 75 C ______________________________________________________________________________________________________ - 71 ppm/K Temperature coefficient of frequency TC ______________________________________________________________________________________________________ Generated: Checked / approved: ______________________________________________________________________________________________________ VI TELEFILTER Vectron International, Inc.
