TFS36D

      The TFS36D is designed as VI telefilter.
      Reference level for the relative attenuation arel of the TFS 36D 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 fc is the arithmetic mean value of the upper and lower frequencies at the 40 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 36 MHz without tolerance. The temperature coefficient of frequency Tcf is valid both for the reference frequency fc and the frequency response of the filter.
      Some important specifications of TFS36D have been concluded into several points as follow. The first one is about its insertion loss which would be typ 25.9dB and max 30dB. The next one is about its nominal frequency at temperature Tot = 45°C which would be typ 36.0 MHz. The next one is about its centre frequency at ambient temperature Ta (fcat) which would be 36,06 MHz. The next one is about its pass band at operating temperature Tot = 45°C which would be from fN - 2,6 MHz to fN + 2,6 MHz. The next one is about its amplitude ripple in PB (p-p) which would be typ 0,45 dB and max. 0,75 dB. The next one is about its amplitude ripple in any 1 MHz increment within 90% of the PB which would be typ 0,35 dB and max. 0,4 dB. The next one is about its group delay ( mean value in PB ) which would be typ 3,15 s and max. 5,0 s. The next one is about its group delay ripple in PB (p-p) which would be typ 50 ns and max. 150 ns. The next one is about its deviation from linear phase in PB (p-p) which would be typ 1,8 ° and max. 2° p-p. The next one is about its triple transit attenuation compared to main signal which would be typ 61 dB. The next one is about its crosstalk which would be 70 dB. The next one is about its temperature coefficient of frequency which would be typ -75 ppm/K. And so on. For more information please contact us.
