| File:TFS188A.doc version 1.2 14.08.2003 VI TELEFILTER Measurement condition Ambient temperature T A: Input power level: Terminating impedances at fc: * Filter Specification TFS 188 A 1/5 25 C 2C 0 dBm input: 1076 output: 831 - 5,8 pF - 6,6 pF Characteristics Remark: Reference level for the relative attenuation a rel of the TFS 188A is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss a e. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed at 188 MHz without tolerance. 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.
