VI TELEFILTER
Measurement condition
Ambient temperature: 23 °C Input power level: 0 dBm Terminating impedances for input: 625 Ω // -6,1 pF for output: 340 Ω // -8,5 pF
Filter Specification
TFS 254 A

Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 254 A 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 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 254,4 MHz without tolerance.
