Characteristics
Remark:
The reference level for the relative attenuation arel of TFS 125D 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 3 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 125,0 MHz without tolerance.
