An international group of astronomers has found that the Cornell University-discovered fast radio burst FRB 121102 – a brief, gigantic pulse of radio waves from 3 billion light years away – passes through a veil of magnetized plasma. This causes the cosmic blasts to “shout and twist,” which will help the scientists determine the source.
Engineers worldwide have been developing alternative ways to provide greater memory storage capacity on even smaller computer chips. Previous research into two-dimensional atomic sheets for memory storage has failed to uncover their potential — until now.
DARPA’s Collaborative Operations in Denied Environment (CODE) program aims to extend the capability of the U.S. military’s existing unmanned aircraft systems (UASs) to conduct dynamic, long-distance engagements of highly mobile ground and maritime targets in contested or denied battlespaces.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don’t work reliably or even at all, such as indoors, in urban canyons, underwater and underground.
Some connected things requiring global coverage and/or mobility will use cellular technologies, but most IoT devices will use noncellular technologies, sharing frequencies in unlicensed bands to communicate with each other and with IoT applications.
Until recently, Traveling Wave Tube Amplifier (TWTA) technology has been the only available option for pulsed field generation. AR now offers high-power solid state pulsed amplifiers at various frequency ranges and output power levels to meet several standards. This white paper presents some of the key features and benefits of AR’s new line of amplifiers, and how to generate high speed and accurate peak RF power measurement capabilities that are ideal for EMC testing, manufacturing testing/troubleshooting, amplifier design/development, and research.
This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.
Time Difference Of Arrival (TDOA), also called multilateration, is a technique for RF emitter geolocation using three or more receivers with algorithms to locate a signal source from the different arrival times at the receivers. This article explains factors that can have an impact on overall TDOA accuracy.
To classify a signal in RF spectrum intelligence gathering, the user must recognize a specific pattern associated with the modulation. Additionally, to recognize a remarkable signal present in received data, the pattern must be distinguished from the noise. Pattern recognition is something that the human brain is good at, but it is more desirable to automate these applications for efficiency and to avoid errors cause by human fatigue.
The Fischer Plastic Series is a family of high performance, fully insulated plastic connector bodies that are all compatible with Fischer’s metallic connectors. Key features include high reliable signal path, high signal and contact density, clear coding for easy operation, and resistance to large temperature variations.
CPI’s Beverly Microwave Division presents the VSC3645 GaN 4.2 kW pulsed solid state power amplifier module operating in the C-band (5.2 – 5.9 GHz). This high efficiency, high power, compact amplifier is highly efficient, easy to maintain, and is designed to easily create high power C-band radar transmitters.
5G – The ultra-reliable technology that increases connection speed everywhere! 5G makes use of technologies originally used for defense, like millimeter waves, massive MIMO and beamforming to fulfill the promise of universal connectivity.
This video offers an introductory tutorial and example of how to bias GaN transistors.
NuWaves introduces the Multi-Octave Radio Frequency (MORF) Up-Converters covering the HF, VHF, and UHF bands, as well as the L- and S-bands. Ideal applications include frequency conversion, signal generation, and system integration.

The Federal Communications Commission (FCC) has reaffirmed that broadband deployment is the top priority to bridge the digital divide in America. The agency says its recent efforts to monitor and accelerate progress in both fixed and mobile services are consistent with its mandate under the 1996 Telecommunications Act, but adds it still has much work to do.
Rohde & Schwarz will be presenting its T&M instruments with the tagline "Oscilloscope innovation. Measurement confidence". Tests on electronic circuits have shown that these instruments significantly increase measurement reliability.
Nordic Semiconductor recently provided a 'sneak peek' of its upcoming nRF91 Series low power cellular IoT solution. During an event in Oslo, Nordic also demonstrated the nRF91 operating on the Verizon Wireless Network in the U.S. and on the Telia network in Norway.
AVX Corporation, a leading manufacturer and supplier of passive components, interconnects, sensors, and control solutions, has released a new series of thin film multilayer chip inductors especially designed to meet demanding performance specifications in automotive signal and power applications.
Software defined architecture, solid-state technology, radio-satellite communications-wireless network integration as well as communicating voice and data/video simultaneously and securely in an increasingly complex spectrum environment will underpin growth for military communications systems and the associated component and semiconductor demand.
In the last couple of years, the RF GaN market experienced an impressive growth and has reshaped the RF power industry landscape. By the end of 2017, the total RF GaN market was close to US$380M, announces Yole Développement (Yole) in this new report titled “RF GaN Market: Applications, Players, Technology, and Substrates 2018-2023”.
