tfs125B.doc Version 1.0 VI TELEFILTER Filter Specification TFS 125 B 1/5 Measurement condition Ambient temperature: Input power level: Terminating impedances: 23 0 50 °C d Bm Ω Characteristics Remark: Reference level for the relative attenuation arel of the TFS 125 B is the minimum attenuation in the pass band. The minimum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency f N is fixed at 125 MHz without tolerance or limit. The values of relative attenuation arel are guaranteed in the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
