Description

      This is the description about TFS80D2  of the VI telefilter Filter specification. Reference level for the relative attenuation arel of the TFS 80 D2 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 reference 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.
      Here are the features: Ambient temperature is 23°C. Input power level is 0dBm. Terminating impedances for input is 50|| - 56 pF; terminating impedances for output is 50|| 0 pF.
      The TFS80D2  absolute Maximum Ratings are these (TA = 25°C). Insertion loss (Reference level) is max. 14,5 dB. Centre frequency at ambient temperature ( fCAT ) is 80,07 ± 0,01 MHz. Pass band (-3 dB) is fC- 100 kHz to fC + 100 kHz. Operating temperature range is from - 25°C+ 75°C. Temperature coefficient of frequency is -0,045 ppm/K². Storage temperature range is from - 30 °C to + 85 °C. Group delay ( mean value in PB ) is 4,12 s. Group delay ripple ( fc 100 kHz to fc) is max. 600 ns. Group delay ripple (fc to fc+ 100 kHz ) is max. 750 ns. Frequency inversion temperature ( To ) is 10°. Frequency deviation of fc over temperature: * ) isfc(Hz) = Tcf(ppm/K) x (T - To)² x fTo (MHz)
