TFS150G3

      The TFS150G3 is designed as VI telefilter.Reference level for the relative attenuation arel of the TFS150G3 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 22,5 dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid both for the reference frequency fc and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating temperature range is not included in the production tolerance scheme.
      Some TFS150G3 important specifications have been concluded into several points as follow.The first one is about its insertion loss which would be typ 28dB and max 30 dB.The next one is about its reference frequency fc at ambient temperature (fCTA) which would be typ 150,25 MHz and limited of 150,25 ± 0,075 MHz.The next one is about its pass band ( PB ) at ambient temperature TA which would be max fC - 14,80 MHz to fC + 14,80 MHz.The next one is about its amplitude ripple in PB (p-p) which would be typ 0,9 dB and max. 1,0 dB.The next one is about its group delay ( mean value in PB ) which would be typ 2,5 s and max 3 s.The next one is about its group delay ripple in PB (p-p) which would be typ 80 ns and max. 180 ns.The next one is about its deviation from linear phase in PB which would be typ 8° p-p (1,5 ° r.m.s.).The next one is about its temperature coefficient of frequency ( Tcf ) which would be typ -87 and would be max -94 ppm/K.The next one is about its frequency deviation of fc over temperature which would be fc(Hz) = Tcf(ppm/K) x (T - TA) x fCTA (MHz).The next one is about its operating temperature range which would be from - 25 °C to + 80 °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 triple transit attenuation compared to main signal which would be 62 dB.The next one is about its crosstalk which would be typ 57 dB.
