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: 25 °C Input power level: 0 dBm Terminating impedance: * Input: 75 ll -41pF Output: 58 ll -45pF Characteristics Remark: The reference level for the relative attenuation arel of the TFS115L is the minimum of the pass band attenuation. This value is defined as the insertion loss ae. The nominal frequency fN is fixed at 115 MHz without any tolerance. The values of relative attenuation arel 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 5.4 dB max. 9.5 dB (reference level) Insertion loss within 2.5dB BW ae + 2.5dB 7.9 max. 12 dB Nominal frequency fN 115 MHz Passband PB fN ± 3 MHz Pass band ripple 0.56 dB max. 0,8 dB Relative attenuation arel fN - 3 MHz … fN + 3 MHz 0.56 max. 2.5 dB fN - 27 MHz … fN - 15 MHz -57 dB min. 40 dB fN - 15 MHz … fN - 11 MHz -52 dB min. 30 dB fN - 11 MHz … fN - 7 MHz -25 dB min. 20 dB fN + 7 MHz … fN + 11 MHz -25 dB min. 20 dB fN + 11 MHz … fN + 15 MHz -41 dB min. 30 dB fN + 15 MHz … fN + 29 MHz -51 dB min. 40 dB fN + 29 MHz … fN + 39 MHz -60 dB min. 50 dB fN + 137 MHz … fN + 147 MHz -75 dB min. 50 dB Group delay ripple in PB GDR 71 ns max. 150 ns IIP3 - min. 30 dBm Triple transit attenuation 39 dB min. 35 dB Return loss in PB 14 dB min. 10 dB Input power - max 10 dBm Operating temperature range OTR - 40 °C ... + 85°C Operable temperature range - 55 °C ... + 85°C Storage temperature range - 45 °C ... + 85°C Temperature coefficient of frequency TCf ** -94 ppm/K *) The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as reference values only. Should there be additional questions do not hesitate to ask for an application note or contact our design team. **) ∆f(Hz) = TCf(ppm/K) x (T-T0) x fcat(MHz). Generated: Checked / Approved: |
