High-power-handling, low-loss (1 dB) microwave phase shifters hold the key to affordable electronically steerable apertures for radar and communications, eliminating the need for active TR modules. Nuvotronics is developing a solid-state approach providing loss performance equal to the best demonstrated MEMS phase shifters, reliably handling five watts peak power with near-zero gain compression, and nanosecond switching time. Using state-of-the-art MMIC processes, our new bit architectures provide flat phase states and low loss over wide bandwidth. In Phase I of this program Nuvotronics developed circuit models of four-bit solid-state phase shifters at S and X-band to show feasibility. Our Phase I program culminated in brassboard demonstration of a C-band 180 degree phase shifter bit with 10 watts power handling using production-released MMIC technology. During Phase II we will demonstrate a four-bit design at X-band that meets power and loss objectives with production cost target of

This proposed program addresses the need for a spaceborne phased array radar system that operates simultaneously at multiple frequency bands for future NASA remote sensing missions dedicated to answering emerging fundamental questions associated with aerosols, clouds, air quality and ecosystems. We will deliver active, electronically scanned array tiles at Ku- and Ka-band utilizing the Nuvotronics PolyStrata® technology for integration alongside an electronically scanned W-band array to form a tri-band system. The PolyStrata® wafer-scale microfabrication process, with capabilities to monolithically integrate dielectric-free antennas with air-coax feed networks in 3D, is a key enabler for achieving state-of-the art performance requirements and manufacturing scalability. Unprecedented power levels will be achieved by integrating state-of-the art GaN MMICs into the PolyStrata front-end architecture.

To meet the needs of future NASA Earth science objectives, significant advancements in the overall level of integration and functional density that is achievable in multi-band microwave radar and radiometer instruments are proposed. The targeted system is the Wideband Instrument for Snow Measurements (WISM), which is a technology development effort to measure Snow Water Equivalent that targets the requirements of the proposed Snow and Cold Land Processes Mission. During Phase I, we developed concepts for enhancing the WISM by incorporating signal multiplexing and active devices in the PolyStrata antenna feed that are not present in the baseline version of the instrument. On the Phase II program, we propose to demonstrate these enhancements to the WISM with deliverable hardware prototypes of such active multi-band feed antennas. Drastic improvements in system noise figure and overall size are made possible by integrating the first stage of LNAs into the PolyStrata feed antenna, eliminating additional cable and diplexer losses that occur in the current modular system.

Traditional millimeter wave designs use split block or waveguide components and large planar filter banks. This implementation is large in mass and size which are at a premium on CubeSats. Nuvotronics proposes to reduce size and weight of these systems by leveraging low-loss PolyStrata-integrated component and interconnects. The PolyStrata process enables highly accurate, repeatable, compact, low loss filters which can stack to further reduce footprint. With savings in weight and size Nuvotronics will increase the total functionality by increasing the number of frequency bands served by a single CubeSat. A recent advancement in switches will be implemented eliminating the need for a motor to control the reflector, creating further reductions in power and weight. A novel interconnect structure will be showcased that can be implemented on any MMICs to provide a manufacturable, low loss, impedance matched method of launching onto MMICs in bands up to 300 GHz.
