Preparing For 5G Millimeter Wave And 6G


Cellular technology is about to take a giant leap forward, but the packaging, assembly, and testing of the chips used in 5G millimeter wave and the forthcoming 6G ecosystem will be significantly more complicated than anything used in the past. So far, most 5G devices are still working at sub-6 GHz frequencies. A massive rollout of mmWave technology over the next few years will significantly ... » read more

From Lab To Fab: Increasing Pressure To Fuse IC Processes


Test, metrology, and inspection are essential for both the lab and the fab, but fusing them together so that data created in one is easily transferred to the other is a massive challenge. The chip industry has been striving to bridge these separate worlds for years, but the economics, speed, and complexity of change require a new approach. The never-ending push toward smaller, better-defined... » read more

Challenges In Packaging 5G And 6G


Millimeter wave frequencies are essential for transferring more data more quickly, but they also require different packaging technology to minimize loss and drift. That opens up a number of tradeoffs around antenna in package, antenna on package, flexible circuits, and different substrates. Curtis Zwenger, vice president of R&D at Amkor Technology, talks about a host of new challenges rangi... » read more

The Development Of Front-End Module For 5G Millimeter-Wave Device Testing


This article describes the development of a front-end module for 5G millimeter-wave device testing. 5G millimeter-wave is planned to be used up to the 53 GHz band. Our challenges are to optimize the performance of our test system up to that frequency band including wide power range of EVM performance, and to add a new one-port S-Parameter measurement function. We describe the elemental technolo... » read more

Making 5G More Reliable


The rollout of 5G is a complex and monumental effort involving multiple separate systems that need to function flawlessly together in real-time, making it difficult to determine where problems might arise, or how and when to test for them. Investments in 5G have been underway for the better part of a decade, and the technology is considered the next huge growth opportunity for mobile devices... » read more

Measuring Frequency Dependence Across 5G mmWave Bands (NIST)


New research paper from NIST, "Methodology for Measuring the Frequency Dependence of Multipath Channels Across the Millimeter-Wave Spectrum." Abstract "Millimeter-wave (mmWave) communications promise Gigabit/s data rates thanks to the availability of large swaths of bandwidth between 10–100 GHz. Although cellular operators prefer the lower portions of the spectrum due to popular belief ... » read more
