TFS246H2.eng 11/96 _________________________________________________________________________________________________________ TELE FILTER tft GmbH SAW filter specification TFS 246H2 1/4 _________________________________________________________________________________________________________ Measurement condition Ambient temperature: Input power level: Source impedance: Load impedance: Ext coil: 23 C -10 dBm 490 || -2.62 pF ( 10%) 490 || -2.62 pF ( 10%) 82 nH Construction see page 2 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 246 H2 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 fN is fixed on 246,000 MHz without tolerance.
