| version 1.3 06.01.02 ______________________________________________________________________________________________________ TFS433B.doc VI TELEFILTER Filter specification TFS 433 B 1/5 ______________________________________________________________________________________________________ Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Terminating impedances: input: output: 50 50 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 433 B 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 fc 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 433,92 MHz without tolerance. The given values for the relative attenuation arel 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.
