Tfs240C.doc version 1.0 12.4.01 ______________________________________________________________________________________________________ VI TELEFILTER www.DataSheet4U.com Measurement condition Ambient temperature: 23 °C Input power level: 0 dBm Terminating impedance: source: t.b.d. load: t.b.d. Filter Specification TFS 240C 1/5 ______________________________________________________________________________________________________ Characteristics Remark: Reference level for the relative attenuation arel of the TFS 240C 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 to 240 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 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.
