The nominal frequency fN is fixed at 1555 MHz without any tolerance or limit. The values of absolute attenuation aabs are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme. D a t a typ. value tolerance / limit Insertion loss ae 3,7 dB 4 dB Nominal frequency fN - 1555 MHz Passband - fN ± 30 MHz Pass band ripple 1,6 dB max. 2 dB Absolute attenuation aabs 1525 MHz … 1585 MHz 3,7 dB max. 4 dB 0,3 MHz … 1480 MHz 32 dB min. 25 dB 1650 MHz … 2500 MHz 28 dB min. 25 dB Return loss within PB 9,5 dB min. 8 ** dB Group delay ripple within PB 10 ns max. 18 ns Input power level - max. 10 dBm Permissible DC voltage - max. 0 V Operating temperature range OTR - - 40 °C ... + 85 °C Storage temperature range - - 40 °C ... + 85 °C Temperature coefficient of frequency TCf * - 72 ppm/K - *) ∆fc(Hz) = Tcf(ppm/K) x (T - TA) x fCTA (MHz) **) at ambient temperature 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. |
