Vectron International Filter specification TFS 1795 1/5 Measurement condition Ambient temperature: 2 C Input power level: dbm Terminating impedance: Input: 5 Ω Output: 5 Ω Characteristics Remark: The maximum attenuation in the pass band is defined as the insertion loss a e. The nominal frequency f N is fixed at 1795 MHz without any tolerance or limit. The values of absolute attenuation a abs 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.
