Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS611A is the minimum attenuation in the pass band. The maximum attenuation in the pass band
is defined as the insertion loss ae. The nominal frequency f
N
is fixed at 611MHz without tolerance or limit. The values of 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 production
tolerance scheme.
