RFPA design flow: the Great Debate; Prof. Steve Cripps, Distinguished Research Professor, University of Cardiff
For many years, PA design has followed two alternative paths: physical and behavioural. Both are quite old and have advantages and disadvantages. The current commercial pressure on designers to adopt the behavioural approach, through new developments such as X-

Field-programmable digital and RF technologies driving innovation in wireless networks; Danny Webster, Principal RF Engineer, Lime Microsystems
Wireless communication networks are going through a major change for providing high data rates, coverage and capacity. The wide spread use of programmable digital technology has enabled a vast array of new wireless applications to be created. In fact, much of the innovation in wireless networks that has supported such a growth in recent years could be attributed to ever increasing levels of functionality within the digital chipsets. On the other hand, RF technology has been providing fixed function for a given design with very little in the way of programmability and flexibility. As we move from one generation of wireless technology to another, this issue has become more prevalent to the extent that today’s RF technology has become a bottleneck, hampering innovation in the design and implementation of future networks. This talk presents the concept of Field programmable RF technology where flexibility is extended from digital to RF domain. Use cases and application areas where such technology is making a significant impact is also presented where the Open Source community are getting behind the technology and driving a Significant level of innovation in the field.

Designing GaN PA MMICs; Liam Devlin, CEO, Plextek RFI
GaN transistors are well suited to the realization of RF and microwave Power Amplifiers (PAs); this is facilitated by their high breakdown voltage and their ability to operate reliably at high junction temperatures. There is an increasing number of commercially available GaN foundry processes and the realization of custom GaN PA MMICs is now a practical option for many applications. This presentation will start with an overview of the structure and operation of a GaN HEMT and will then explain how to design a GaN PA MMIC. Design examples will be presented for several applications each using a different commercially available GaN foundry processes. Watch video
