| TFS235A.doc version 1.6 01.06.2001 VI TELEFILTER Filter Specification TFS 235A 1/5 Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Terminating impedances for input: 1,38 kOhm // -1,5 pF for output: 1,38 kOhm // -1,5 pF Characteristics Remark: Reference level for the relative attenuation arel of the TFS 235A is the insertion loss. The insertion loss ae is defined as the minimum of attenuation in pass band. 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 on 235,008 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 also 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.
