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. The given values for the relative...
