VI TELEFILTER
Measurement condition Ambient temperature: 23°C Input power level: 0dBm Terminating impedances *) for input: 3,2 kΩ ||- 5,6pF for output: 3,1 kΩ || -6.2pF Characteristics
Filter specification
TFS 111B
1/5
Remark: The reference level for the relative attenuation arel of TFS 111B is the minimum of the pass band attenuation amin. This value is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 20,0 dB filter attenuation level relative to the insertion loss ae.
