The Adaptive RF Technology (ART) program aims to significantly advance the hardware used in communication radios by developing a fully adaptive and reconfigurable architecture that is agnostic to specified waveforms and standards. ART-enabled “cognitive” radios would be able to reconfigure themselves to operate in any frequency band with any modulation and for multiple access specifications under a range of environmental and operating conditions.
It can cost up to $100 million and take more than two years for a large team of engineers to design custom integrated circuits for specific tasks, such as synchronizing the activity of unmanned aerial vehicles or the real-time conversion of raw radar data into tactically useful 3-D imagery. This is why Defense Department engineers often turn to inexpensive and readily available general-purpose circuits, and then rely on software to make those circuits run the specialized operations they need.
The explosive growth in mobile and telecommunication markets has pushed the semiconductor industry toward integration of digital, analog, and mixed-signal blocks into system-on-chip (SoC) solutions. Advanced silicon (Si) complementary metal oxide semiconductor (CMOS) technology has enabled this integration, but has also led to a rise in costs associated with design and processing. Driven by aggressive digital CMOS scaling for high-volume products, Intellectual Property (IP) reuse has emerged as a tool to help lower design costs associated with advanced SoCs.
Radio Frequency and mixed signal electronics face performance limitations due to the limited circuit complexity possible in typical high-speed/high-dynamic-range compound semiconductor integrated circuit technologies.
The Direct On-Chip Digital Optical Synthesizer (DODOS) program seeks to create a technological revolution in optical frequency control analogous to the disruptive advances in microwave frequency control in the 1940s.
