2002 VI TELEFILTER Measurement Condition Ambient temperature: Input power level: Source impedance: Load impedance: Terminating impedances: *) 23 0 200 50 input: output: Filter Specification C dBm balanced single ended 880 // -11,0 pF 890 // -12,6 pF TFS 125 G 1/5 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 125G is the attenuation at 125 MHz.
Reference for the echo response attenuation is the main time response lobe, the reference time is defined as t0.
The nominal frequency fN is fixed at 125 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.
