eBooks by Topic:
Advances in Radar and Components
Several of the articles in this eBook cover improvements due to GaN technology including a survey of GaN foundries covering the various processes in production and in development and electronically reconfigurable GaN amplifiers recently introduced by Qorvo. It also covers a giga-watt, multi-way combiner using corrugated coaxial waveguide filters and a mmWave MIMO radar configuration. The eBook also looks at how startups are revolutionizing automotive radar with new 4D sensors for ADAS and autonomy.
The Growing Importance of Timing Solutions for 5G and IoT
Timing and synchronization are critical to 5G communications and much more demanding than they were for 4G networks. 5G networks require lower latency, higher data rates, higher frequencies (in many cases) and more devices. This eBook starts off with an overview of the features in 5G Release 16, reviewing the new applications and potential in this specification. Next it looks at the role of satellites in 5G networks in covering rural and remote areas while being part of the 5G network as a whole. Then, the eBook digs into the importance of oscillators in the timing and synchronization followed by an article that covers how oscillators need to provide low jitter while minimizing power consumption and footprint for next generation optical networks.
mmWave Technologies and Product Innovations
mmWave is the industry’s newest frontier, a free space resource that has triggered a “gold rush” of technology horses and applications riding them. This eBook samples a few of these applications and the challenges facing them. The first article, “Using E-Band for Wideband SatCom: Opportunities and Challenges,” contributed by Hughes Network Systems, describes the requirements for and challenges with E-Band links between the earth and geostationary satellites. The new article “Virtual Cable Calibration for OTA Testing of 5G mmWave Devices” by Rohde & Schwarz describes the concept and how it is used to ensure compliance to the 3GPP standards. The article “6G: Innovating the Future of Wireless Communications,” submitted by Keysight Technologies, surveys a few of the use cases being discussed and the consortiums formed to explore them. Wide bandwidth at sub-THz frequencies is a shared theme. “Satcom, the New mmWave Frontier,” also contributed by Keysight Technologies, returns to mmWave satellite links, specifically the difficulty making accurate and repeatable measurements, particularly OTA. The article “5G Fixed Wireless Access Array and RF Front-End Trade-Offs,” contributed by Qorvo, outlines the design of a fixed wireless access system for a suburban neighborhood, including the design of the phased array and trade-offs among the semiconductor technology options for the front-end module. Concluding the eBook, an article from Qorvo discusses phase noise, an important parameter that can limit the data rate of communications systems.
