TFS120A

Filename: tfs120a.doc Version 1.2 04.09.2003 VI TELEFILTER Filter specification TFS120A 1/5 Measurement condition Ambient temperature: Input power level: Terminating impedance: * Input: Output: 23 0 1180 1110 °C dBm || -7,1 pF || -7,9 pF 2. Characteristics Remark: Reference level for the relative attenuation a rel of the TFS 120A is the insertion loss. The insertion loss ae is defined as the insertion loss at the nominal frequency fN . The centre 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 a e. The temperature coefficient of frequency Tcf is valid for both the reference frequency fc and the frequency response of the filter on the operating temperature .
