Remark:
Reference level for the relative attenuation arel of the TFS 119A is the insertion loss. The insertion loss ae is defined as the insertion loss at the
nominal frequency f
. 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 f
N
is fixed on 119.6 MHz without tolerance. The specified values have to be reached in
operating temperature range.
