TFS 238.doc version 2.1 05.09.2003 VI TELEFILTER Measurement condition Ambient temperature TA: Input power level: Terminating impedances at fc *: Filter Specification TFS 238 1/5 23 C 0 dBm input: 450 output: 430 // -8,3 pF // -7,3 pF Characteristics Remark: The reference level for the relative attenuation arel of TFS238 is the minimum of the pass band attenuation amin. This value is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 1 dB filter attenuation level relative to the insertion loss ae. The given values for the relative attenuation a rel and 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.
