Tfs70g.doc version 1.0 06.01.02 ______________________________________________________________________________________________________ VI TELEFILTER Filter specification TFS 70 G - Page 1 / 3 ______________________________________________________________________________________________________ Measurement condition Ambient temperature: Input power level: Source impedance: Load impedance: 23 °C 0 dBm 50 Ω and test adapter 50 Ω and test adapter Characteristics Remark: Reference level for the relative attenuation arel of the TFS 70 G is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fo is the arithmetic mean value of the upper and lower frequencies at the 3dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 70,00 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 fo 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 fo.
