Ameya360:Renesas and AMD to Demo Full RF, Digital Front-End Design for 5G AAS Radios at MWC 2023

　　Renesas Electronics Corp. will showcase a full RF front end solution for 5G Active Antenna Systems (AAS) radios in collaboration with AMD at the Mobile World Congress in Barcelona, February 27–March 2.　　Paired with the field-proven AMD Zynq UltraScale+ RFSoC Digital Front End OpenRAN Radio (O-RU) Reference Design, the RF front end includes RF switches, low-noise amplifiers and pre-drivers. It offers a complete solution to meet the demand of the growing mobile network infrastructure market. The reference platform will be demonstrated at the AMD booth (#2M61 Hall 2).　　The new 5G design platform integrates all the essential RF and digital front-end hardware for base stations operating in the Open Radio Access Network (O-RAN) ecosystem. This includes a high-isolation multi-throw DPD (Digital Pre-Distortion) switch, a high-gain and linearity pre-driver in a compact package, an integrated switch and Low Noise Amplifier (LNA) with input signal coupling functionality. This full RF front end platform is designed to efficiently process and transmit data to wireless networks with optimized power levels. Moreover, it has been integrated with the AMD RFSoC DFE ZCU670 Evaluation Kit for quick prototyping and rapid development of wireless network systems. The platform offers superior RF performance, while minimizing DPD resources for TX channel linearization, improving radio efficiency and ultimately reducing operating costs for wireless network providers.　　The RF front-end solution is the latest 5G solution to be jointly developed by Renesas and AMD. Previously, the two companies collaborated on the high-performance RF timing solution for 5G Next-Gen Radio (5G NR), which incorporates Renesas’ IEEE 1588-enabled System Synchronizer as part of the DFE ZCU670 Evaluation Kit.　　“We are thrilled to be collaborating with AMD once again to demonstrate our latest RF capabilities at the upcoming Mobile World Congress,” said Naveen Yanduru, Vice President of RF Engineering at Renesas’ Infrastructure Business Division. “Using our turnkey hardware solution, developers of 5G RF wireless infrastructure systems can reduce development time and cost. We are confident that this solution will set a new standard in RF performance and efficiency for the wireless communication market.”　　“The RFMC expansion connectors on the ZCU670 evaluation board allow our customers to quickly prototype and evaluate a complete RF line up design for their Radio. To demonstrate, we have collaborated with Renesas again to develop an optimized RF Front End reference design targeting the N78 band,” said Brendan Farley, Corporate Vice President of Wireless Engineering at AMD. “As the market for OpenRAN 5G Radio (O-RU) continues to grow, these reference designs will help accelerate our mutual customers’ time to market with proven solutions.”

Apple is changing GaAs’ future

After a quiet period due to the saturation of the mobile handset industry, the GaAs wafer market wakes up.  The technical choice made by Apple creates a real and vast enthusiasm for GaAs solutions. 3D sensing in mobile phone as well as LiDAR’s applications are giving a new breath for GaAs substrates suppliers.Under its new technology & market report “GaAs Wafer & Epiwafer Market: RF, Photonics, LED and PV applications”, Yole Développement (Yole) announces a 15% CAGR between 2017 and 2023 (in volume), with an impressive 37%, especially for photonics applications (1).GaAs analysis from Yole proposes a comprehensive overview of the GaAs wafer and epi wafer industry. This report outlines Yole’s understanding of the industrial landscape, its evolution as well as the technical challenges. The analysts are offering a relevant technical description of GaAs wafer and epiwafer growth. Market size and forecasts are also delivered in four big applicative markets: RF, Photonics, LED, and PV. Photonics applications are driving the GaAs wafer and epiwafer market into a new era. Yole’s analysts invite you to discover the latest GaAs technology and market trends. As one of the most mature compound semiconductors, GaAs has been ubiquitous as the building block of power amplifiers in every mobile handset. In 2018, GaAs RF business represents more than 50% of the GaAs wafer market. However, market growth has slowed down in the past couple years due to the handset market’s gradual saturation and shrinking die size. “At Yole, we expect GaAs to remain the mainstream technology for sub-6 GHz instead of CMOS, owing to GaAs’ high power and linearity performance as required by carrier aggregation and MIMO technology,” explains Dr. Hong Ling, Technology and Market Analyst at Yole.Since 2017, GaAs wafer has been particularly notable in photonics applications. When Apple introduced its new iPhone X with a 3D sensing function using GaAs-based lasers, it paved the way for a significant boost in the GaAs photonics market. GaAs wafers market segment for photonics applications should reach US$150 million by 2023.“GaAs-based ROY and infrared LED applications have also caught our attention”, asserts Dr. Ezgi Dogmus, Technology & Market Analyst at Yole. “We estimate, 2017-2023 CAGR achieves 21% (in units) for the total GaAs LED market, surpassing more than half of GaAs wafer volume by 2023.”In terms of the wafer and epiwafer businesses, each application requires a different size and quality when determining wafer and epiwafer prices. As a new entrant, photonics applications will impose new specification requirements compared to the well-established RF and LED wafer and epiwafers, creating significant ASP diversity.From a value chain point of view, the GaAs photonics market’s remarkable growth potential will offer plenty of opportunities for wafer, epiwafer, and MOCVD equipment suppliers, as well as for investors.GaAs wafer supply: Sumitomo Electric, Freiberger Compound Materials, and AXT, involved in GaAs wafer supply, lead the market with about 95% of market share collectively. And since new laser applications have very high specification requirements for GaAs wafer that are constantly evolving, Yole analysts’ expect the top players to maintain their technical advantage for at least another 3 – 5 years.Regarding GaAs epiwafer production, Yole’s analysts identified different business models. The GaAs LED market is principally vertically integrated, with very well-established IDMs like Osram, San’an, Epistar, and Changelight. In parallel, GaAs RF businesses outsource significantly from well-established epihouses.Within the GaAs photonics market, the epi business is still applications-dependent. GaAs datacom market segment is mostly epi-integrated, with dominant IDMs like Finisar, Avago, and II-VI. For 3D sensing in smartphones, epi outsourcing is significant.In 2017, Apple’s supplier Lumentum used IQE as its VCSEL epi supplier. This resulted in an almost 10x increase in IQE’s stock price. Other leading GaAs epihouses are in qualification or ramping up. Yole expects the photonic epiwafer market to behave similar to the GaAs RF epiwafer market.
