Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS1774 is the minimum attenuation in the passband. The maximum attenuation in the passband
is defined as the insertion loss ae. The nominal frequency fN is fixed at 1774.9 MHz without any tolerance or limit. The values of relative attenuation arel
are guaranteed over the whole operating temperature range. The frequency shift of the filter within the operating temperature range is included in the
production tolerance scheme.
