High Performance Phase Shifter Design for Antenna Array Applications

Antenna arrays with switching beams are enablers of new generation of communications systems. Phase shifters used in an antenna array should have high linearity, high switching speed and high-power handling capacity. To address this challenge, high performance phase shifters using new architectures of RF switches will be explored and developed in this project. The main aims of the project are 1) to examine and identify the technologies and architectures suitable for realization of high-speed RF switches; 2) design phase shifters using these switches; 3) test and improve the linearity and power handling capacity of the phase shifters.

This focused project, funded by a major international telecom company, will be undertaken at the High Frequency Engineering Group at the University of Liverpool which is a world-leading group in the field of RF/microwave engineering and device design. An inter-disciplinary team in the Group has significant experience in the design and testing of the RF devices for the front-end of communications systems. We are seeking to appoint an intelligent and highly motivated individual with the strong background in microwave engineering and device design to undertake this three-year PhD research programme. A candidate should have a very good degree (1st or high 2.1 Class BEng or MSc) in electrical engineering, specialising in microwave/RF engineering and design. A good knowledge of RF circuit analysis techniques, RF simulators, and microwave materials would be a bonus. He/she must be a technically competent and committed to work enthusiastically with the research team to develop and validate novel technologies for the development of high-performance phase shifters for emerging mobile communications systems.
