TFS125K

TFS125K.doc Version 1.2 18.06.2003 VI TELEFILTER Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Terminating impedance’s : 50 Filter Specification TFS 125K 1/5 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 125K is the maximum attenuation in the pass band. The maximum attenuation in the pass band is defined as the insertion loss a e. The nominal frequency fN is fixed at 125 MHz without tolerance or limit. The values of relative attenuation a rel 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.
