TFS112E

TFS112E 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 is 500 ||-6,9 pF for input and 600 ||-6,1 pF for output.

What comes next is about the characteristics of TFS112E. The typical insertion loss (ae=amin) is 13,5 dB and the maximum is 14 dB. The typical reference frequency (fc (30 dB-BW)) is 112,32 MHz. Then is about the relative attenuation (arel). The maximum arel is 3 dB at fc to fc ± 475 kHz and 10 dB at fc ± 475 kHz to fc ± 815 kHz. The minimum arel is 20 dB at fc ± 1175 kHz to fc ± 1300 kHz and 30 dB at fc ± 1300 kHz to fc ± 1475 kHz. The minimum arel is 40 dB and the typical is > 45 dB at fc ± 1475 kHz fc ± 10 MHz. The permissible DC voltage (VDC) is 12 V. The permissible AC voltage (Vpp) is 10 V. The frequency inversion temperature (To) is + 40. The operating temperature range is from -20 to + 85.

The last one is about the remarks of TFS112E. Reference level for the relative attenuation arel of the TFS112E 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 30 dB filter attenuation level relative to the insertion loss ae. The nominal frequency is fixed on 112,32 MHz.
