Organizer: Jan Budroweit, DLR, Germany

The half-day workshop aims to introduce the general workflow for space missions as seen from agencies like ESA or DLR and the requirements for a successful development and final operation in space. In this workshop, the topics space mission and hardware design are addressed: talking about critical mission phases, constraints in space hardware design and development and on how common pitfalls can be avoided. Two invited talks are presenting the lessons learned and best practice experience for scientific payloads that have been designed, developed and successful demonstrated space.

Artificial Intelligence (AI) appears to be one of the most rapid growing technologies in this decade. Statistics show that for 2019 the AI market experienced a growth of 154%, and is expected to grow until 2025 by more than 140% every year. Therefore, AI technologies found their way into numerous technlogical branches including Radar based technologies. This Workshop will give a broad overview on the capabilities of AI-based Radar technology starting with basic ideas on perceptio-action cycle based cognitive radar methods. Further talks will discuss a variety of several applications utilizing AI, including gesture recognition, classification and tracking of vulnerable road users as well as several safety relevant applications. The workshop will close with an open panel discussion on recent achievements and future research directions of AI-based Radar technologies.

Mobile cellular subscribers reached more than 6 billion in 2021 and 5G LTE brings high data capacity as low latency using sub-6GHz and mm-Wave spectrum. The workshop presents the status of 4G/5G LTE RF Front End Modules (RF FEM) and techniques to deliver an over gigabit-per-second data rate such as Carrier Aggregation and MIMO as well Wider Modulation Bandwidth for LTE and mm-Wave spectrum. The high-speed wireless ecosystem which includes 5G LTE and WiFi 6 (802.11ax) which is currently deployed uses two frequency domains: sub 6GHz frequency domain and mm-Wave spectrum. Mm-Wave will be used initially to increase the capacity for backhaul network and allow low latency. Also, the mobile devices started to have new wireless functionality in 6GHz-8.5GHz spectrum such as Ultra-wideband (UWB) for proximity indoor location. The RF FEMs integrate power amplifiers, switches, couplers, tuners, and active acoustic filters. The workshop will cover practical design aspects for 5G FEMS with emphasis for FEM architectures, power amplifiers, switches, and active filters as well the technologies involved into these designs. The workshop will also cover aspects of new 5G LTE integration for envelope tracking and LNA design.

Terahertz (THz) technology is a leading candidate to meet emerging 6G wireless system requirements. However, there are many challenges, including severe path loss, low device efficiency, and large-scale beamforming using dense phased arrays. The talk will discuss possible research directions to overcome these challenges. Latest D-band phased array system prototyping activities and feasibility test results will be presented. Also, issues related to SATCOM deployments through efficient phased arrays will be presented. Challenges and opportunities around front-end electronics like power amplifiers for these mmWave phased arrays will also be discussed.

Organizer: Tumay Kanar, Sr Manager, mm-wave IC Design at Renesas Electronics

The latest advancements in lower-earth-orbit (LEO) satellite constellation technology demonstrates a promising path for a high speed and low latency connectivity across the globe. Long-term success of these constellations heavily depends on large scale commercial availability of ground terminals. Average cost of a conventional phased array panel will need to scale down by a few orders of magnitude and it will require a completely new approach on system implementation. This target can only be achieved by much higher integration both at the system and RF front-end level. Silicon content in RF front-end will increase significantly and become a key enabler for highly integrated systems.

This workshop will outline the advanced practices and techniques on the system level and address the key integrated circuit technologies for silicon-based phased array RF front-ends by demonstrating how integration in silicon enables low-cost implementation for commercially available ground terminals for next generation satcom networks.
