Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 270A2 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.
