When vacationers buy a stake in a beachfront timeshare, they decide in advance who gets to use the property when. The National Institute of Standards and Technology (NIST) is helping the Federal Communications Commission (FCC) institute a similar plan for when commercial wireless providers and the U.S. Navy attempt to share a desirable 150-megahertz (MHz)-wide section of the radio frequency (RF) spectrum for communications.
A radio telescope at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has received a significant upgrade, advancing from one dish to four. The upgrades are part of the Laboratory’s ongoing effort to test the merits of a radio telescope for a potential future project between national labs and DOE-sponsored universities. The scientists’ ultimate goal is to look deep into the universe and gain a better understanding of periods of accelerated expansion and the nature of dark energy.
Cellular technologies have advanced from first generation analog technologies to advanced high-performance fourth generation and fifth generation systems in just four decades. Despite the increase in complexity of wireless standards and devices, cellular technologies maintain a set of common principles that form the basis behind the design of cellular systems. This white paper explores these basic principles and examine the underlying technologies that lay the foundation for today and future cellular systems.
The Internet of Things is providing exciting opportunities to enhance products for consumer, industrial, medical and others. This paper discusses these unlicensed wireless connections and the special testing required to meet government regulations for IoT devices with a primary focus on the United States Federal Communications Commission (FCC).
New RFSoC technologies add RF-class analog to digital and digital to analog data converters to Xilinx’s already powerful MPSoC, ARM processor enhanced family of high-performance FPGAs. The implications of its use changes the way engineers could design and package small, high-channel count systems for 5G, military, and scientific applications. This white paper takes a look at the current trends in data converters and signal processing to better understand the capabilities of RFSoC and how to best use the advantages of the technology.
This article covers key parameters in the selection of RF inductors and what parameters should be considered first in the process.
