TFS420H

      TFS70H43 is a very good product.Here you can get some information about the measurement condition.The ambient temperature (T_A) is 23.The input power level is 0 dBm.The terminating impedances is 61 //-9.0 pF for input and is 81 //-8.9 pF for output.
      What comes next is about the characteristics.The typical insertion loss (Reference level) (a_e) is 8.2 dB and the maximum is 10 dB.The maximum norminal frequency (f_N) is 420 MHz.The typical centre frequency (at ambient temperature) is 421.7 MHz.The maximum pass band  is f_N±15 MHz.The typical pass band ripple is 0.5 dB and the maximum is 1 dB.The typical relative attenuation (a_rel) is 43 dB and the minimum is 40 dB at f_N-410 MHz to f_N-25 MHz.The typical arel is 42 dB and the minimum is 40 dB at f_N+25 MHz to f_N+180 MHz.The typical arel is 55 dB and the minimum is 25 dB at f_N+180 MHz to f_N+580 MHz.The maximum phase linearity (p-p) within PB is 12 deg.The typical VSWR is 1.4:1 within f_N ±12 MHz and the maximum is 1.5:1.The typical VSWR is 1.6:1 within f_N ±15 MHz and the maximum is 1.8:1.The operating temperature range is from +65 to + 75.The storage temperature range is from -40 to + 85.
