DC-35 GHz low-loss MMIC switch using 50 nm gate-length MHEMT technology for ultra-low-power applications

This work addresses the need for devices with ultra-low-power consumption in the areas of telecommunications and sensors. The MMIC has the lowest power consumption 50nm GaAs MHEMT SPDT switch with exceptionally high performance. In addition, the technology is compatible with mainstream microelectronics fabrication, allowing system integration with reduced chip size, weight and cost. The paper led to a BAE Systems grant to develop High Speed Sampling Down-converters for Radar and EW Applications (£81k). The technology has also been transferred to Kelvin Nanotechnology (www.kelvinnanotechnology.com/), a company wholly owned by the University which provides services to industry and research.
