Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 116 is the insertion loss. The insertion loss ae is defined as the insertion loss at the
nominal frequency f_N . 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 116.6 MHz without tolerance. The specified values have to be reached in
operating temperature range.
