TFS43A.doc version 1.4 05.12.03 VI TELEFILTER Description IF filter for digital cable TV Preliminary Specification TFS 43 A 1/5 Measurement condition Ambient temperature TA: Input power level: Terminating impedance: 25 C 0 dBm source: 50 load: 2k II 3 pF Characteristics Remark: Reference level for the relative attenuation arel of the TFS 43A is the insertion loss. The insertion loss ae is defined as the insertion loss at the nominal frequency fN . 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.
