Abstract
Broadata Communications, Inc. (BCI) proposes to development a novel Direct Digital Synthesizer (DDS) for high power radio frequency (RF) amplifiers. The development of this DDS is in response to the Navy's requirement for the development of a technique topre-distort the signal fed to a high power RF amplifier in such a manner as to reduce distortion components to a point lower than -40dBc. This technology will combine digital synthesis and digital pre-distortion with efficiency enhancement to boost RFpower amplifier efficiency and, at the same time, reduce cross modulation distortion often associated with higher efficiency power amplifiers. This device will be fabricated using the latest available, off-the-shelf commercial technology. It will besuitable for high power and high efficiency base station applications. Phase I will focus on hardware architecture design and algorithm simulation. In Phase II, a RF power amplifier, driven by the DDS with pre-distortion compensation, will be built todemonstrate the feasibility of the systems.The proposed DDS power amplifier approach is applicable to both, military and commercial markets. High efficiency power amplifier translates into lower battery weight or longer usage and lower costs. Togetherwith low distortion generated by DDS with predistortion for today's highly complex and stringent modulation schemes, the proposed technology is a win-win solution for the wireless communication industry.
