The maser (microwave amplification by stimulated emission of radiation), the older microwave frequency sibling of the laser, was invented in 1954. However unlike lasers, which have become widespread, masers are much less widely used because in order to function they must be cooled to temperatures close to absolute zero (-273°C).
Monitoring in real time what happens in and around our bodies can be invaluable in the context of health care or clinical studies, but not so easy to do. That could soon change thanks to new, miniaturized sensors developed by researchers at the Tufts University School of Engineering that, when mounted directly on a tooth and communicating wirelessly with a mobile device, can transmit information on glucose, salt and alcohol intake.
For the past three years, an important broker has had its eyes on a prime piece of property that it wants to allocate to multiple tenants to ensure maximum use.
Alaska’s super-power High-Frequency Active Auroral Research Program (HAARP) transmitters in Gakona, Alaska, will fire up again for the spring research campaign April 6 – 14. University of Alaska Fairbanks (UAF) Space Physics Group researcher and HAARP Chief Scientist Chris Fallen, KL3WX, told ARRL that more than 40 hours of “externally funded” experiments are in the queue.
How does Wireless InSite differ from planning tools? The most important differences emerge when users need to simulate 5G millimeter-wave and MIMO systems. This paper presents 10 cues that your organization may need a channel-modeling tool to supplement your 5G network planning efforts.
An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. The AF varies with frequency at the same presented field strength, but at a different frequency, the produced voltage at the connector is not constant. This white paper explains the process of creating AF data and how to use it.
Many products incorporate electronics and wireless communications and need RF interference testing. This requires shielding enclosures that need proper testing to ensure their correct operation.
The US Marines' “mega-drone" is intended carry the same payload as an F-35B and fly a radius of up to 700 nautical miles at 30,000 feet. This Marine Air Ground Task Force Unmanned Aircraft System-Expeditionary (or MUX, for short) also will be able to fill “an extremely broad range of missions."
This white paper focuses on the time domain analysis displays generated from vector network analyzers (VNAs). The paper will also cover frequency domain basics, an in-depth overview of how a time domain display is created from frequency domain data (S-parameters), and steps for applying the time domain display to common problems in RF systems.
Dielectric Laboratories (DLI) offers a series of single layer capacitors designed with Class II dielectric materials and X7R temperature stability characteristics for a variety of DC blocking or RF bypass applications. With operation capabilities over a broad frequency range, these high frequency, wire bondable capacitors are ideal for GaN, GaAs, filtering, tuning, and coupling applications where small size and microwave performance is vital for a circuit’s performance.
NuWaves Engineering offers the NuFilter™ series of cavity filters designed for applications operating within the 1 GHz to 20 GHz frequency range. Options for standard and custom models include 3 dB bandwidths from 3% to 28%, stop-band rejections of 80 dB, insertion losses of < 1 dB, and up to 50 W power handling (higher power ratings available upon request).
High peak-to-average power ratios (PAPRs) are not beneficial as they challenge the non-linear power amplifier operation close to compression in order to reach maximum efficiency. Possible solutions for include crest factor reductions (CFR), such as clipping high signal peaks. This video demonstrates a simple technique to clip any waveform, including the Verizon Wireless 5GTF signal, with the use of software tools for signal generation and analysis.

Altair will hold its 2018 Global Altair Technology Conference at the Palais des Congrès in Issy, Paris, France from October 16 –18. This year’s event will focus on sharing amazing applications of Simulation-Driven Innovation from technology leaders and industry executives from all over the world.
It is estimated that by 2020 more than 26 billion devices will be connected to the internet of things (IoT). By using cellular telecommunications bands and existing wireless networks, a low power wide area network (LPWAN) radio technology standard known as narrowband IoT (NBIoT) will be used to support a wide range of IoT devices and services.
The Johanson Manufacturing branded Variable Inductors, from Knowles Precision Devices, combine small size and high performance with non-magnetic properties. Inductors and variable inductors are necessary elements of many RF products. They are used for matching and loading low noise amplifiers, power amplifiers and mixers, as well as for providing frequency- selective resonant circuits in variable-frequency oscillators.
Researchers, policy makers and others in academia and industry will gather for the fifth anniversary of the annual Brooklyn 5G Summit at New York University's Tandon School of Engineering.
