Abstract:
1. An amplification unit comprising: a signal splitter, wherein the signal splitter is operable to split an input signal into a first signal and a second signal such that the two resulting signal portions are in quadrature; a main amplifier, wherein the main amplifier is formed from at least one semiconductor having a first material composition and the main amplifier is operable to amplify the first signal to produce a first amplified signal; an auxiliary amplifier, wherein the auxiliary amplifier is formed from at least one semiconductor based on silicon (Si) semiconductor materials, wherein the first material composition is substantially different from the second material composition, and the auxiliary amplifier is operable to amplify the second signal to produce a second amplified signal; and a signal combiner, wherein the signal combiner is operable to combine the first amplified signal and the second amplified signal, and realign the phase of the first amplified signal and second amplified signal.
