Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS810 is the minimum of the pass band attenuation amin. The minimum attenuation in the
pass band is defined as the insertion loss ae. The nominal frequency
f
N
is fixed at 810 MHz without any tolerance or limit. The values of relative
attenuation arel are guaranteed for the whole operating temperature range. The frequency shift of the filter in the operating temperature range is
included in the production tolerance scheme.
