5G took some fifteen years to develop, starting around 2004 at university research labs. When 3GPP Release 15, the first 5G new radio (5GNR) standard, was approved in late 2017, the race to deploy began. That includes mmWave Frequencies starting around 24 GHz. At roughly the same time, research labs began looking at frequencies above…

While the wireless carriers, equipment suppliers, and component suppliers have cranked up the 5G marketing hype, there is some resistance to deploying the technology because of health concerns. There is some credible evidence in the science regarding health effects resulting from exposure to RF energy. In 2019, Larry Desjardin looked at the science in a…

  With 5G ramping up and much of it operating below 6 GHz, engineers need to generate and analyze signals in the FR1 band. Signal Hound, a maker of PC-connected RF signal sources and spectrum analyzers, now offers Linux support for its software. You are now free to develop your own applications for the company’s…

To minimize issues from standing waves, engineers have long used Faraday rotation isolators that let forward-traveling signals pass to the load while attenuating reverse-traveling signals such as reflections. Higher frequencies, however, bring a new set of problems such as insertion loss that Micro Harmonics claims to have solved with its mmWave isolators. The series consists…

Pasternack announces a comprehensive portfolio of 5G RF solutions serving the urgent needs of engineers and technicians around the world with high-grade RF components and cable assemblies shipped same-day to support 5G innovation, testing and deployments. The “RF Components for the Next Generation” suite is comprised of thousands of active, passive, interconnect and antenna products…

The radio frequency spectrum, the basis for wireless telecommunications, is a finite resource that needs to be managed effectively to satisfy the demands posed by the exponential growth in wireless internet access. IMDEA Networks researchers have developed a novel communications architecture for future ultrafast wireless networks that promises to achieve data rates previously only possible…

A team of scientists from DESY and the University of Hamburg has achieved an important milestone in the quest for a new type of compact particle accelerator. Using ultra-powerful pulses of laser light, they were able to produce particularly high-energy flashes of radiation in the terahertz range having a sharply defined wavelength (colour). Terahertz radiation…

Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University’s Brown School of Engineering. They’re also tougher, more flexible and can essentially be painted onto devices. The Rice lab of chemical and biomolecular engineer Matteo Pasquali tested antennas made of “shear-aligned” nanotube films. The…

Fairview Microwave, Inc., an Infinite Electronics brand and a leading provider of on-demand RF, microwave and millimeter wave components, has released a new series of high-reliability, temperature conditioned RF cable assemblies that are ideal for military electronics, avionics, SATCOM, ECM, IFF and other mission critical applications. Fairview’s new low loss, pre-conditioned, high-reliability cables cover operating…

Renesas Electronics Corporation announced a new radiation-hardened 16-channel current driver with integrated 4-bit decoder for reducing the size, weight and power (SWaP) of satellite command and telemetry systems. The ISL72814SEH integrates the decoder, input level shifter, and 16 current driver arrays in a single monolithic IC. The device allows satellite manufacturers to significantly increase system capacity…
