TFS120C

TFS120C is a kind of VI telefilter. There are some information about the measurement condition. The ambient temperature is 23. The input power level is 0 dBm. The terminating impedances at fN is 1270 || -11,7 pF for input and 4330 || -2,9 pF for output.

What comes next is about the characteristics of TFS120C. The typical insertion loss (Reference level)) (ae) is 27 ± 0,5 dB and the maximum is 33 dB. The nominal frequency (fN) is 120,0 MHz. The typical centre frequency (fC at ambient temperature (fCAT)) is 120,01 MHz. The pass band is from fN - 4,5 MHz to fN + 4,5 MHz. The maximum arel (Relative attenuation) is 3 dB at fN to fN ± 4,5 MHz. The minimum arel is 40 dB and the typical is from 42 to 70 dB at fN ± 5 MHz fN ± 25 MHz. The typical arel is 70 dB at fN - 120 MHz to fN - 25 MHz and fN + 25 MHz to fN + 300 MHz. The permissible DC voltage (VDC) is 12 V. The permissible AC voltage (Vpp) is 10 V. The operating temperature range is from -20 to + 75. The storage temperature range is from - 40 to + 85.

The last one is about the remarks of TFS120C. Reference level for the relative attenuation arel of the TFS120C 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 nominal frequence fN is fixed at 120,0 MHz without tolerance or limit.
