ABSTRACT:
Generally stated, an apparatus and method for routing a digitized radio frequency (RF) signal 140-143 to a plurality of paths is described herein. In accordance with a first preferred embodiment, the apparatus comprises a digital upconverter/modulator (DUC) 125, 129 coupled to a scaling and switching network 100N which is comprised of, at minimum, a first, second, third and fourth digital switch, and a first, second and third adder. Within the scaling and switching network 100N, the first digital switch is responsive to the DUC 125,129. The first adder is responsive to the first and second digital switches, while the second adder is responsive to the third and fourth digital switches. Finally, the third adder is responsive to the first and second adders.
