1 Vectron International Filter specification TFS 281 1/5 Measurement condition Ambient temperature: 23 C Input power level: 0 dbm Terminating impedance: * Input: 183 Ω pf Output: 172 Ω pf Characteristics Remark: The reference level for the relative attenuation a rel of the TFS281 is the minimum of the pass band attenuation. This value is defined as the insertion loss a e. The nominal frequency f N is fixed at 281,6 MHz without any tolerance. The values of relative attenuation a rel 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.
