TFS1575G

      The TFS1575G is designed as VI telefilter.The maximum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 1575,42 MHz without tolerance or limit. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
      Some TFS1575G important specifications have been concluded into several points as follow.The first one is about its insertion loss which would be typ 3.5dB and max 5.0dB.Thw next one is about its nominal frequency which would be max 1575.42MHz.The next one is about its pass band which would be max fN ± 1.0 MHz.The next one is about its pass band ripple which would be typ 0.5dB and max 1.0dB.The next one is about its pass band variation which would be typ 1.0dB and max 1.5dB.The next one is about its absolute attenuation which would be typ 65dB and min 50dB for 1475.42MHz and would be typ 55dB and min 45dB for 1525.42MHz and would be typ 54dB and min 45dB for 1625.42MHz and would be typ 54dB and min 45dB for 1675.43dB. The next one is about its VSWR within PB which would be typ 1.4 : 1 and max 1.6 : 1. The next one is about its operating temperature range which would be from -30 °C to + 85 °C.The next one is about its storage temperature range which would be from -45 °C to + 85 °C.The next one is about its temperature coefficient of frequency which would be typ -41ppm/K.
      Also there are some TFS1575G stability characteristics, reliability about it.The first one is about its shock which would mean 500g, 1 ms, half sine wave, 3 shocks each plane; DIN IEC 68 T2 - 27.The next one is about its vibration which would mean 10 Hz to 500 Hz, 0,35 mm or 5 g respectively, 1 octave per min, 10 cycles per plan, 3 plans; DIN IEC 68 T2 - 6.
