TFS125L

Filename: tfs 125l.doc Version 1.2 15.10.2004 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedance: * Input: Output: 23 0 °C dBm Filter specification TFS 125L 1/5 650 Ω || -14,5 pF 750 Ω || -12,8 pF Characteristics Remark: The reference level for the relative attenuation arel of the TFS 125L is the minimum of the pass band attenuation. This value is defined as the insertion loss ae. The nominal frequency fN is fixed at 125 MHz without any tolerance. 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.
