“In the dynamic 5G infrastructure market, there is a continuous race for more efficient antenna types. Switching technology from RRH to AAS will transform the RF front ends from a low number of high-power RF lines to a large number of low-power RF lines” asserts Ahmed Ben Slimane, PhD, Technology & Market Analyst, Compound Semiconductor Monitors at Yole Développement (Yole).

“For mobile connectivity, Wi-Fi 6 began to enter the market in 2019”, explains Poshun Chiu, Technology & Market Analyst, Compound Semiconductors & Emerging Materials at Yole.  And he adds: “Some OEMs launched new phones with Wi-Fi 6: Samsung’s Galaxy S10 in Q1-19, Apple’s iPhone 11 in Q3-19, and in Q1-20 Xiaomi was the first Chinese handset company to have Wi-Fi 6. GaAs solutions are becoming of great interest owing to their linearity and high power output, compared to traditional solutions”.
More information is available in a dedicated article “GaAs RF: stronger than ever” published on i-Micronews, this week.


“Following the global Covid-19 outbreak, almost all automotive OEMs had to shut down and the supply chain faced significant disruption,” comments Ezgi Dogmus. “In this context, we expect the power SiC market’s Y-o-Y (year over year) growth to slow down to 7% in 2020, with a significant impact in Q1-2020 and Q2-2020.”
In addition, the reverse engineering & costing company System Plus Consulting, a Yole Développement company, deeply analyzes the compound semiconductor and power technologies and technical choices made by the leading semiconductor players. In this regard, we invite you to discover the interview with Amine Allouche, Technology & Cost Analyst at System Plus Consulting: The importance of SiC semiconductors for energy efficiency for EETimes.
