TFS 270 B 1/5
Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 270B 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 nominal frequency fN is fixed on 270,000 MHz without
tolerance. The values of the pass band ripple and the relative attenuation arel are guaranteed in the whole operating temperature
range. The frequency shift of the filter in the operating temperature range is included in the measurement tolerance scheme.
