New Materials, Devices and Circuit Techniques for RF

Brought to you by The Radio Technology Group

Since its beginning, the needs of radio communications have been intrinsically linked with innovation, entrepreneurialism and technological advancement.

Registration for this event is now closed.

About the event

From the coherer of the wireless telegraphy, through to the cat's whiskers detectors in early crystal radios to the vacuum triodes used today, progression for RF is fast-moving and exciting.This event will reflect the dynamism and innovations in RF and their impacts on new materials, devices and circuit techniques. These may be new materials such as graphene, or “meta-materials” made by forming microstructures on conventional materials. New active and passive devices, for example MEMs resonators, could enable new approaches to filtering and new ways to design circuits that make use of these innovations.

This event will deliver a myriad of presentations to describe how technologies and innovations in the development of new materials, and their viable options for numerous applications can deliver fundamental leaps in RF.

Today we have an essentially universal method to make electronics circuits - whether computers or radios - based on silicon VLSI and other well-known ways of fabricating circuits. However, as we demand more from radio systems, new enabling technologies logically facilitate the next wave of product innovation. ‘New Materials, Devices and Circuit Techniques for RF will explore and question some of these innovations, including:  


  • Graphene or "meta-materials: a world of possibilities made by forming microstructures on conventional materials.
  • New active and passive devices: the exciting potential of MEMs resonators and how they can be used to enable new approaches to filtering and designing circuits.

Registration & Networking over lunch


Introduction to the Cambridge Wireless Radio Technology SIG from John Haine of u-Blox


Welcome from our host Simon Bond of Silicon South West


Welcome from our joint lunch sponsor, Rohde & Schwarz


Welcome from our partner, Stuart Revell of ICT KTN


Handset Antenna Design; Dr Sampson Hu, CTO of Smart Antenna Technologies

Smart Antenna Technologies uses software re-configurable hardware to enable manufacturers to cover all functions and bands (2G, 3G, 4G LTE, WiFi, Bluetooth, GPS and etc.) and produce one device for all territories, reducing costs, streamlining manufacturing and logistics. This talk will review the handset antenna history, including different type of handset antennas, and their limitation and then introduce SAT innovated antenna technology and how it will be deployed in current and future wireless systems.




Plasma Silicon Devices (PSiDs) in Wireless Networks; Dr David Hayes, Founder and CEO of Plasma Antennas Ltd

A plasma silicon device (PsiD) can perform beam-forming and beam-selection operations in a single monolithic microwave integrated circuit (MMIC). The MMIC works by reflecting an RF signal off electronically controllable solid state plasma, trapped within a parallel plate waveguide. This RF technology has applications from 1GHz to 100GHz. Targeted uses for the PSiDs include small cell backhaul and extended range (>10m) WLAN, operating at the higher microwave and millimetre wave frequencies, (e.g. 60GHz). The talk will review the latest advancements in the technology, its functionality within various antenna configurations and how it will to be used in future wireless systems.




Circuit and Technology Solutions to Address the Multi-Mode Mobile Terminal Front-End Challenge; Chris Clifton, CTO and Divisional Director, Sony EU

This talk will focus on a number of radical but practical technology and circuit solutions for addressing the size, performance and cost challenges associated with multi-mode, wideband mobile terminals.




Refreshment break over networking


Graphene for RF and Microwave Applications: Potential and Challenges ‘Is graphene really the wonder material for high frequency applications?; Dr Hatice Tuncer, Research Associate, Cambridge Graphene Centre and the Engineering Department of Cambridge University

Graphene transistors with projected ft at 1.4 THz may be promising to fulfil the ITRS 2015 requirements; however issues such as the lack of current saturation remain unresolved. Out-of-the-box thinking could lead to novel applications of this unique 2D material rather than compete with current technology. The Cambridge Graphene Centre, established in February 2013, is running collaborative research between the University of Cambridge and Queen Mary College – University of London assessing the suitability of graphene for the microwave and THz regimes. The talk will cover issues with CVD graphene from synthesis to device construction while relating physical properties to high frequency design metrics using simulation tools and measurements.




Efficient Linear Power Amplifiers for use in 4G systems; Dr Kevin Morris, Reader in Radio Frequency Engineering, Bristol University

There are a number of methods of producing linear efficient amplifiers that are currently receiving a great deal of attention within the power amplifier research community. As the bandwidths of signals has risen to up to 20MHz per channel and signals required to be amplified now have peak to average power ratios of greater than 10dB, this has led to the need for new approaches to amplifier linearisation. This talk will describe the latest research into two promising techniques used for efficient linear amplifier design, the Inverse Doherty amplifier and the Non-Linear Envelope Tracking (NET) technique. These techniques are both capable of amplifying 4th generation signals with efficiencies of greater than 50%.

Chris Clifton - CTO & Divisional Director:Europe based Sony Semiconductor & Electronic Solutions (SES), Sony Europe B.V.

Chris is the Chief Technology Officer and Divisional Director for Europe based Sony Semiconductor and Electronic Solutions (SES) with responsibilities for new technology/product incubation and telecommunication/semiconductor R&D activities. His main mission is to identify and help accelerate the development of core enabling technologies which will underpin future consumer and industrial electronic products. Current research focus areas include 3GPP related technologies which will pave the way towards the 5G era including the wireless M2M connectivity technologies which will underpin the next IoT revolution. He currently serves on the ETSI board.

A significant period of his time at Sony has been spent managing the Wireless Semiconductor Development activity in Basingstoke, joining the Sony Semiconductor operation in 1997. During this time the company succeeded in securing significant design wins in the European cellular phone market. After spending a period of time at the main development site in Atsugi, Japan, the design flow for the GaAs MMIC technology was transferred to the UK Design Centre so that European products could be designed locally.

Following the successful set-up of the MMIC design facility by Chris and his team, other areas of Mixed-Signal development were expanded at the Basingstoke facility including cellular RF transceivers, full Bluetooth chipset solutions and analogue devices for DTV applications, under his leadership. In 2001, he became Divisional Director for Wireless products within the European Development Centre.

In 2006, Chris launched a local design centre for the development of LCD panels for mobile consumer electronics devices. Since this time, he has maintained a strong interest in display and image capture technologies, in addition to several other strategically important microelectronic technologies such as MEMS.

Prior to Sony, he held positions as Chief Design Engineer at the GEC III-V semiconductor facility at Caswell and RF Engineering Manager at DSC Communications.

As well as being a member of the Institute of Electrical Engineers (IEE) and Chartered Engineer (CEng), Chris has served on the boards of a number of UK government bodies covering training and promotion of engineering within the UK. Also a member of the UK Strategy Advisory board for 5GIC (5G Innovation Centre at Surrey University).

He has authored more than 20 international publications and holds a number of patents. Academic qualifications include a BSc(Hons) in Physics and a PhD in Electronic Engineering.
