TFS810

This is the description about TFS810 of the VI development specification. Reference level for the relative attenuation arel of the TFS810 is the minimum of the pass band attenuation amin. The minimum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 810 MHz without any tolerance or limit. The values of relative attenuation arel are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.

Here are the TFS810 features: Ambient temperature is 23°C. Input power level is 0dBm. Terminating impedances for input is 200. Terminating impedances for output is 200.

The TFS810 absolute maximum ratings are these (TA = 25°C). Insertion loss (Reference level) is max. 4,0 dB. Nominal frequency is 810,0 MHz. Pass band is fN 8,5 MHz. Amplitude ripple within PB is max. 1 dB. Group delay mean value in PB is max. 100 ns. Group delay ripple within PB is max. 75 ns. Operating temperature range is from 0 ° to +70° C. Storage temperature range is from -40 ° to +80° C. Temperature coefficient of frequency is T.B.D. The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as reference values only.
