KG 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. Measurement condition Ambient temperature: 23 °C Input power level: 0 dBm Terminating impedance: Input: 50 Ω Output: 50 Ω Characteristics Remark: The maximum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 922,5 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 1,2 dB max. 3,3 dB (reference level) Nominal frequency fN - 922,5 MHz Passband PB - fN ± 2,5 MHz Pass band ripple p-p 0,5 dB max. 2,0 dB Absolute attenuation aabs 0,3 MHz ... 600 MHz 44 dB min. 40 dB 600 MHz ... 900 MHz 43 dB min. 38 dB 955 MHz ... 1075 MHz 41 dB min. 32 dB 1075 MHz ... 1495 MHz 51 dB min. 43 dB Return loss within PB 18 dB min. 8 dB Input power level - max. 15 dBm Operating temperature range OTR - - 45 °C ... + 85 °C Storage temperature range - - 45 °C ... + 85 °C Temperature coefficient of frequency TCf * - 36 ppm/K - *) ∆fc(Hz) = Tcf(ppm/K) x (T - To) x fCAT (MHz).
