| TFS248F.doc Version 3.0 15.11.2002 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedance: input: output: 23 C 0 dBm Filter Specification TFS 248F 1/5 50 ; unbalanced; no matching network 200 ; balanced, no matching network Characteristics Remark: Reference level for the relative attenuation arel of the TFS 248 F is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae . The nominal frequency fN is fixed at 248,6 MHz. The given values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below even if the centre frequency fc is shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the centre frequency fc.
