VI TELEFILTER
Measurement condition
Ambient temperature TA: Input power level: Terminating impedance at fc: input: output: 23 °C 0 dBm
Filter Specification
TFS 249A
1/5
1,15 kΩ || -6,5 pF 1,05 kΩ || -6,5 pF
Characteristics
Remark: Reference level for the relative attenuation arel of the TFS 249A is the minimum of the pass band attenuation amin . It is defined as the insertion loss ae. 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 ae. The nominal frequency fN is fixed on 249,6 MHz without tolerance.
