| version 1.1 06.01.02 TFS82B.doc ______________________________________________________________________________________________________ SAW- Filter ______________________________________________________________________________________________________ Filter specification TFS 82 B 1/2 Measurement condition Ambient temperature: Input power level: Source Impedance: Load Impedance: 23 C 0 dBm 582 || -21,5 pF 3,18 k || -5,81 pF Construction and pin connection see page 2 50 test circuit see page 2 Characteristics Remark: Reference level for the relative attenuation arel of the TFS82B 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 nominal frequency is fixed on 82 MHz. The centre frequency f0 is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss ae.
