TFS80A

      The TFS80A is designed as VI telefilter.
      Reference level for the relative attenuation arel of the TFS80A  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 80,0 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.
      Some TFS80A  important specifications have been concluded into several points as follow. The first one is about its insertion loss which would be max. 16,5 dB. The next one is about its nominal frequency which would be max 80.0MHz. The next one is about its pass band which would be from fN - 100 kHz to fN + 100 kHz. The next one is about its group delay absolute delay from fN - 100 kHz to fN + 100 kHz which would be typ 4,55 s and max 4,85 s. The next one is about its group delay ripple from fN - 100 kHz to fN + 100 kHz which would be max 600 ns. The next one is about its temperature coefficient of frequency which would be -0,045 ppm/K2. The next one is about its frequency inversion temperature which would be 23 °C. The next one is about its operating temperature range which would be from -20 °C to + 85 °C. The next one is about its storage temperature range which would be from -40 °C to + 85 °C. The next one is about its permissible DC voltage which would be 12 V. The next one is about its permissible AC voltage which would be 10 V. And so on. For more information please contact us.
