Researchers Develop New Energy Efficient Transmitter Design

The future of a number of our daily activities depends on how robust the telecommunication industry improves its technology. Smart devices are gaining ubiquity and broadband Internet and wireless communications are integrating them together.

Recognizing the need for futuristic 5G applications, a group of researchers at the Georgia Institute of Technology have developed a design of antenna and electronics that can boost the energy and spectrum efficiencies of a millimeter ware transmitter. This newly designed transmitter has enhanced modulation and generates lesser waste heat, which is expected to result in longer talktime and high rates of data transfer.

The new hybrid device has the ability to simultaneously optimize millimeter wave antenna and electronics, using conventional integrated circuits (ICs) and conventional materials, which means no additional change will be needed for the manufacturers in terms of manufacturing and packaging.

The key aspect of the new design is to maintain optimum energy efficiency despite the device functioning at its average of peak output power. It must be understood that traditional transmitters only have high efficiency during peak power usage while it drops significantly during low power levels, which in turn results in low efficiencies overall. Beyond energy efficiency, the new design is expected to enable spectrum efficiency by enabling highly complex protocols of modulations. According to the lead author, the new transmitter can relay six to ten times greater data rate within the same channel bandwidth, paving way to the freedom of design innovation.

Additionally, this cross-disciplinary new design can aid to the fabrication and function of multiple transmitters and receivers within the same chip, which means even thousands of elements can work together as a system.
