Abstract
A digital up-converter (DUC) includes conjugate-mixer-combiner. The conjugate-mixer-combiner includes a pre-combiner configured to generate combinations of a first in-phase (I) value to be transmitted at a first frequency of a first frequency band, a first quadrature (Q) value to be transmitted at the first frequency of a first frequency band, a second I value for to be transmitted at a second frequency of a second frequency band, and a second Q value to be transmitted at the second frequency of a second frequency band. The conjugate-mixer-combiner further includes a plurality of multipliers collectively configured to shift the combinations based on an average difference between the first frequency and the second frequency.
