| Filename: 448.doc version 1.1 16.05.2002 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedances * Input: Output: 23 C 0 dBm Filter Specification TFS 448 1/5 340 || -1,05 pF 340 || -1,05 pF Characteristics Remark: Reference level for the relative attenuation arel of the TFS448 is the maximum of the pass band attenuation amax. The maximum of the attenuation within the usable signal bandwidth is defined as the insertion loss ae. 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 448,0125 MHz without tolerance. The given values for the relative attenuation 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.
