TFS114A

TFS114A 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 source impedance is 485 ||-11.9 pF. The load impedance is 485 ||-11.9 pF. The ext coil is 540 nH.

What comes next is about the characteristics of TFS114A. The centre frequency (fo) is -114,0 MHz (at room temperature). The maximum insertion loss (Reference level)) (ae=amin) is 6 dB. The minimum 3 dB - bandwidth is 152 kHz, the maximum lower 3 dB-frequency is fo - 76 kHz and the minimum upper 3 dB-frequency is fo + 76 kHz. The maximum arel (Relative attenuation) is 15.5 dB at fo + 200 kHz, 18.5 dB at fo - 200 kHz, 31 dB at fo + 400 kHz, 32 dB at fo - 400 kHz, 40 dB at fo ± 1 MHz to fo ± 2 MHz and 45 dB at fo ± 2 MHz to fo ± 20 MHz. The frequency inversion temperature + 25. The operating temperature range is from -20 to + 70.

The last one is about the remarks of TFS114A. Reference level for the relative attenuation arel of the TFS114A is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae.
