1 / 5 page Tfs869.doc version 1.2 22.09.03 VI TELEFILTER Filter specification TFS 869 1/5 TELEFILTER GmbH Potsdamer Stra ße 18 D 14 513 TELTOW / Germany Tel: (+49) 3328 4784-0 / Fax: (+49) 3328 4784-30 tft@telefilter.com Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Terminating impedances: input: 50 output: 50 Characteristics Remark: The maximum of the pass band attenuation amax is defined as the insertion lossae. The nominal frequency fN is fixed at 869,0 MHz without tolerance. The given values for the absolute attenuation ae 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. D a t a typ. value Variation/ Limitation Insertion loss ae = amax 1,8 dB max. 3,0 dB Nominal frequency fN - 869,0 MHz Centre frequency fc 869,0 MHz Passband PB 8,6 MHz fN ± 1,0 MHz absolute attenuation arel fN ± 20,0 MHz .... fN ± 23,0 MHz 42 dB min. 35,0 dB fN ± 41,0 MHz .... fN ± 44,0 MHz 42 dB min. 40,0 dB Input power level - max. 17,0 dBm Temperature coefficient of the frequency TCf*) -32 ppm/K - Operating temperature range - 30 °C ... + 80 °C Storage temperature range - 40 °C ... + 85 °C *) fc(Hz) = Tcf(ppm/K) x (To - TA) x fCAT (MHz) Generated : Checked / approved: VI TELEFILTER reserves the right to make changes to the product(s) and/or information contained herein without notice. No liability is assumed as a result of their use or application. No rights under any patent accompany the sale of any such product(s) or information. |
