TFS112A

TFS112A 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 fc is 565 |-6,5 pF for input and 650 |-5,7 pF for output. The Q-value of matching elements is from 50 to 70.

What comes next is about the characteristics of TFS112A . The typical insertion loss (ae=amin) is 13,5 dB and the maximum is 14 dB. The typical reference frequency (fc (BW(-30 dB)) is 112,320 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 ± 5,0 MHz. The permissible DC voltage (VDC) is 12 V. The permissible AC voltage (Vpp) is 10 V. The maximum input power level is +10 dBm. The operating temperature range is from -20 to + 85. The storage temperature range is from -25 to + 90.

The last one is about the remarks of TFS112A . Reference level for the relative attenuation arel of the TFS112A is the minimum of the passband attenuation amin. The minimum of the passband 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.
