| file: TFS460B.eng version 2.1 4/98 ______________________________________________________________________________________________________ VI TELEFILTER SAW filter specification TFS 460 B 1/4 ______________________________________________________________________________________________________ Measurement condition Ambient temperature: 23 C Input power level: 0 dBm Source impedance: 263 || -0,45 pF Load impedance: 263 || -0,45 pF Construction, pin connection and 50 test circuit see page 2 Stability characteristics and packing see page 3 Air reflow temperature conditions see page 4 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 460 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 centre frequency fo is the arithmetic mean value of the upper and lower frequencies at the 2 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 460 MHz without tolerance.
