Researchers from ITMO University developed a method to enhance the activity of enzymes by using radio frequency radiation. The method requires making a special complex consisting of enzymes and magnetic nanoparticles.
Researchers at ETH Zurich have developed a modulator with which data transmitted via millimetre waves can be directly converted into light pulses for optical fibres. This could make covering the “last mile” up to the internet socket at home considerably faster and cheaper.
Plus, automakers and energy companies chase their own 5G networks, the "Internet of Lifesaving Things," a U.S. lawmaker demands a "5G safety determination" from the FCC, and more, all in this edition of The Week In 5G.
A great deal of confusion exists surrounding RF over fibre via coarse wavelength division multiplexing (CWDM), or dense wave division multiplexing (DWDM). This article aims to clarify the differences between the two methods, as well as discuss the challenges associated with both technologies.
This paper presents results from modeling RF propagation in a mine using Wireless InSite®. The Edgar Mine in Idaho Springs, CO provided the realistic scenario for the model. The path loss exponent was evaluated for a 5m section of the modeled mine by considering three different materials and three different standard deviation of surface roughness values for dry granite. When comparing this simulated data with data retrieved from the Edgar Mine it was determined that the Uniform Theory of Diffraction (UTD) ray tracing code, of Wireless InSite, can portray a communications system within a mine environment.
This paper presents results from sea to land propagation using Wireless InSite®. The effort explores the effects of various elements in the scene and how they impact the results. The various elements in the scene include the ships out at sea, the ships docked, the docks themselves, the buildings around the dock area, and the material properties of each.
The basic amplifier design and mode of operation have remained relatively unchanged until recently. This white paper discusses recent advancements in amplifier design that provide flexibility and efficiency, creating a new class of “smart amplifiers.” These new amplifiers allow for user-defined, dynamic, and simultaneous variation of the core amplifier parameters during operation, and enable the optimization of performance for an extremely wide range of applications.
The automotive industry is continuously being equipped with more radar sensors that support drivers in critical situations. Radar makes it possible to quickly and precisely measure the radial velocity, range, azimuth angle and elevation angle of multiple objects, so it is often used in advanced driver assistance systems (ADAS).

dB Control offers a new dB-4150 smart microwave power module (MPM) consisting of a solid state amplifier and a vacuum power booster. It is designed to provide 100 Watts pulsed/CW RF output power, and operate in the 6 to 18 GHz frequency range.
EMI Filters are used to prevent electromagnetic interference in avionics and aircraft systems, as well as military shipboard/vehicle electronics, and in military communication systems. Electromagnetic interference can cause a complete loss of data in communications systems, or a simple decline in data quality.
Narda Safety Test Solutions demonstrates a dynamic range comparison of different spectrum analyzers and receivers. This video compares the best-in-class handheld spectrum and network analyzer, portable radio monitoring receiver, and real-time spectrum analyzer.
Today’s shift towards faster 4G networks has transformed our world with entirely new mobile apps with higher connectivity. In the growing Internet of Things, these faster networks are extremely important for the seamless transfer of high amounts of data. 5G networks are the future technology that will connect the world we live in.
Skyworks offer two new front-end modules (FEMs) for GNSS/GPS/GLONASS/Galileo/Compass/QZSS radio receiver applications in the 1559 to 1606 MHz frequency range. The SKY65933-11 and the SKY65943-11 feature an integrated low noise amplifier (LNA), and a pre-filter and post-filter. Both devices use surface-mount technology (SMT) in the form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost solution.
Skyworks’ newest family of compact, high performance RF front-end modules (FEMs) is specifically designed for LPWAN – supporting LoRa®, SigFox and other unlicensed band technologies – as well as high-power Industrial, Scientific, Medical (ISM) applications operating in the 860-930 MHz frequency range. These new solutions deliver improved sensitivity and more than quadruple the operating range versus a standalone system-on-chip (SoC).
