The reference level for the relative attenuation arel of the TFS 70AM 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 at 70 MHz. The values for relative attenuation are guaranteed at
ambient temperature. The frequency shift of the filter over temperature defined by the temperature coefficient of frequency Tc
f
is not included in the
production tolerance scheme.
