About the Project

Applications are invited for PhD candidates on the themes described below, as part of The University of Sheffield’s Communications Research Group and EPSRC National Millimetre Wave Measurement Laboratory.

Details

Research and design of RF systems and circuits continues to be a field where practitioners are in high demand and are setting the international direction of future communication technologies, such as for 5G and 6G.

In particular, the field of Millimetre Wave (mmWave) circuit design has experienced a resurgence of interest, due to emerging usage in 5G and anticipated increased use in future 6G mobile and fixed systems. Systems operating at circa 28GHz, 73GHz and sub-THz are all becoming important.

Underpinning future communications equipment will be cost-effective and low power (yet high performance) RF circuits and hardware, spanning the entire field and spectrum of RF design.

The purpose of this research project is to investigate present state-of-the-art aspects of mmWave and Microwave RF circuit design and then choose an area for further research that is interesting to the candidate and complements the Group’s activity. The research topic will be chosen from one or more of (but not limited to) the following themes, as relevant to the Group’s ongoing research activity:-

·       Low power RF modulators / demodulators

·       Fundamental and Subharmonic mixers

·       RF Sampling transceiver architectures

·       Wideband modulators / demodulators (e.g. 5 and 6 Port concepts)

·       PCB & MMIC implementation of low-power, high-performance transceivers and subsystems

·       High performance tunable and reconfigurable oscillators and frequency synthesisers

·       Cost effective and power efficient circuits for RF antenna beam forming and steering

Researchers can expect to become involved in designing novel hardware and related DSP or control software for their proposed system(s) and then trialling and enhancing them for optimal operation in the Lab and in field trials. The project will be part of an ongoing activity in 5G & 6G next generation mmWave systems, also involving a wide range of industry partners. The Communications Research Group is working on multiple areas of wireless communications technology including mmWave, sub-THz communications, propagation measurement and IoT systems. The technology emerging from the researcher's project will contribute to these research themes.
