| TFS45A.doc version 1.2 06.01.02 _____________________________________________________________________________________________________ VI TELE FILTER Filter Specification TFS 45 A - 1/2 _____________________________________________________________________________________________________ Measurement condition Ambient temperature: Input power level: Terminating impedances: Characteristics 23C 10 dBm 50 and matching network Remark: Reference level for the relative attenuation arel of the TFS 45 A is the minimum of the pass band attenuation amin. The minimum of the pass and attenuation amin is defined as the insertion loss ae. The centre frequency fo is the arithmetic mean value of the upper and lower frequencies at the 3dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid both for the reference frequency fc and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating temperature range is not included in the production tolerance scheme.
