| TFS248D.doc version 2.1 14.09.00 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedance: source: load: 23 C 0 dBm 630 || -5,6 pF 600 || -5,7 pF Filter Specification TFS 248 D 1/5 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 248 D is the minimum of the pass band attenuation amin. This value is defined as the insertion loss ae. The nominal frequency fN is fixed to 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 also if the centre frequency fo 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 fo.
