Load impedance . Filter specification TFS 35A 1/5 25 °C 0 dBm for input: for output: 50 . 50 . 310. 690 -25,7 pF. -10,1 pF. 2. Characteristics : Remark: Reference level for the relative attenuation a rel of the TFS 35A is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss a e. 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 nominal frequency fN is fixed at 35,42 MHz without tolerance. All specified values are guarantied in operating temperature range. Measurement of filter response will be done at temperatures of –40 °C , 25 °C and 85°C for each part.
