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 Output: 50 Characteristics Remark: The maximum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 850 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 in PB ae 1.4 dB max. 3.5 dB Nominal frequency fN - 850.0 MHz Passband PB - fN ± 7 MHz Bandwidth BW 2 dB 32 MHz min. 30 MHz 2 dB 32 MHz max. 35 MHz 40 dB 49 MHz max. 120 MHz Absolute attenuation aabs 0.3 MHz … 815 MHz 35 dB min. 32 dB 885 MHz … 1500 MHz 38 dB min. 32 dB Group delay ripple within PB 23 ns max. 50 ns Return loss within PB 12.5 dB min. 11 dB Operating temperature range OTR - - 45 °C ... + 85°C Storage temperature range - - 45 °C ... + 85°C Temperature coefficient of frequency TCf * -42 ppm/K *) ∆fc(Hz) = Tcf(ppm/K) x (T - To) x fo (MHz).
