Measurement condition Ambient temperature T A: Input power level: Terminating impedances at fc * ) : Source impedance: Load impedance: 23 C 0 dBm. for input: for output: 50 50 953 1275 - 8,93 pF. - 7,32 pF. 2. Characteristics Remark: Reference level for the relative attenuation arel of the TFS 70H28 is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae. The reference frequency fc is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss ae . The temperature coefficient of frequency Tcf is valid both for the reference frequency f c and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating temperature range is not included in the production tolerance scheme Data Insertion loss (Reference level) Centre frequency at ambient temperature T A Pass band at ambient temperature TA: Amplitude ripple (p-p): Bandwidth 1 3 20 40 45 dB dB dB dB dB arel MHz MHz MHz MHz ae fc PB typical values 25 dB 70,01 MHz tolerance / limit max. 26 dB 70 0,09 MHz fC - 1,5 MHz ... fC + 1,5 MHz fC ..... fC 1,20 MHz 0,35 dB max. 0,8 dB at ambient temperature: 2,75 MHz 3,15 MHz 4,41 MHz 4,61 MHz 4,71 MHz 2,77 s 50 ns 2,3 54 60 Quartz 20...40 C -0,045 ppm/K fc(Hz) = Tcf(ppm/K) x (T - To) x fTo (MHz) - 25 C ... + 80 C - 40 C ... + 85 C min. 2,50 MHz min. 3,00 MHz max. 4,90 MHz Relative attenuation : fC .... fC 1,25 fC 1,25 MHz .... fC 1,50 fC 2,45 fC 4,45 MHz ....
