1) Digital Pre-Distortion and Post-Correction from DC to RF and mm-Wave towards Optical Spectrum

Organizers: Hermann Boss, Rohde & Schwarz; SungWon Chung, University of Southern California


This workshop overviews recent advancements in digital pre-distortion (DPD) and digital post-correction (DPC) techniques for a wide range of applications including 4G/5G base stations, mobile handsets/portables, ADC/DAC based next-generation wireline transceivers, and advanced optical communication systems with a high spectrum efficiency. DPD techniques are essential to 4G/5G wireless communication systems, which demand a greater bandwidth and a higher energy efficiency. For DPD on wireless communication, there are growing interests on nonlinearity modeling and characterization, adaptive pre-distorters, and observation receivers for RF and mm-Wave power amplifiers employed in massive MIMO arrays, intra-band and inter-band carrier aggregation, envelope tracking, outphasing, and load modulation. With wireline communication, to advance the data rate limit, designers are leveraging a high-order modulation, which requires a digital-to-analog converter (DAC) based transmitter along with an analog-to-digital converter (ADC) based receiver. Recent work in ADC design show that dynamic nonlinearities become a critical challenge in realizing ADCs and DACs with unprecedentedly high performance well beyond the conventional limits. To enable next-generation high performance data converters, DPC and DPD techniques to mitigate the impact of such dynamic nonlinearities thus become essential. The recent trend of using a high-order modulation continues with optical communication with Tb/s data rate, a reliable and low-power implementation of DPC and DPD is important now more than ever.

2) Solid State Power Amplifiers for Space

Organizers: Václav Valenta, Iain Davies and Natanael Ayllon, European Space Agency


This workshop will provide a general overview of solid-state power amplifiers (SSPAs) and their use in space applications. The main SSPA building blocks will be discussed in detail together with the key semiconductor technologies that are used in space-borne SSPAs today. Examples of SSPAs in use and in development for key missions will be shown.

The space environmental challenges in which the RF equipment operates will be presented as well as the practical measures that need to be taken to assure high level of reliability. Reliability, derating principles for space components and qualification procedures will be discussed.

Moreover, in the frame of the workshop, introduction to MMIC high power amplifier design will be given. The latter will address the whole MMIC HPA design chain: beginning with typical MMIC HPA specifications, selection of transistor cells, corporate power combining and matching networks and stability analysis.

3) Microwaves, CubeSats, and Small Satellites

Organizers: Rick Sturdivant, Azusa Pacific University , William Deal and Charlie Jackson, Northrop Grumman Corp


CubeSats and small satellites are on the front line of the NewSpace revolution that has been emerging in recent years. A recent report by BIS Research projects the global nanosatellite market to be $6.35B by 2021 with a compound annual growth rate approaching 40%. Although the market and growth rate for this technology are promising, these goals will not be achieved without the fundamental technology of microwave and millimeter-wave components and subsystems. CubeSats and other small satellites are the leading edge for many new applications, providing low cost opportunities and chances to perform early testing of concepts on orbit. This workshop will discuss the required circuits, subsystems, microwave receivers and antenna technology. In addition, several applications will be described.
