Abstract
A signal amplification system including a plurality of digital signal inputs coupled to a signal combination devices, wherein each of the plurality of digital signal inputs correspond to a separate digital signal, a signal conversion device coupled to the signal combination device, an up-conversion device coupled to the signal conversion device, and an amplification unit coupled to the up-conversion device. The plurality of signals are combined into a combined digital signal in the signal combination device, the combined digital signal is converted into a combined analog signal in the signal conversion device, the combined analog signal is up-converted into an up-converted analog signal in the up-conversion device, and the up-converted analog signal is amplified into an amplified output in the amplification device. Various systems and methods to combine and amplify digital signals and analog signals.
