Scientists at the Massachusetts Institute of Technology (MIT) Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a wireless device as a non-invasive alternative to body-worn sensors and electrodes. The new sensor uses radio signals to monitor sleep quality by relying on artificial intelligence to measure stages of sleep: light, deep, or rapid eye movement (REM).
Professor Sean Hum and his research group in in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering (ECE) developed the radio-frequency design of a novel deployable antenna in collaboration with members of the University of Toronto Institute for Aerospace Studies (UTIAS) Space Flight Laboratory (SFL), with the aim of reducing launch volume and mass.
NYU Wireless has developed what is thought to be the world’s first commercial emulator for 5G millimeter wave (mm-Wave) systems. The emulator differs from the existing paradigm because it performs not only the emulation of the wireless channel, but also of the beamforming antenna arrays on both the transmitter and receiver devices under test (TX and RX DUTs).
Multiplexing, the ability to send multiple signals through a single channel, is a fundamental feature of any voice or data communication system. An international research team has demonstrated for the first time a method for multiplexing data carried on terahertz waves, high-frequency radiation that may enable the next generation of ultra-high bandwidth wireless networks.

Leveraging a long heritage of engineering innovation in YIG and low phase noise technologies, Teledyne Microwave Solutions (TMS) has developed a brand new line of YIG synthesizers that substantially reduces the high cost of acquiring a high-quality, broadband low phase noise source. After many years of building the industry's lowest phase noise YIG Oscillators, TMS has applied that expertise to deliver on a longstanding industry aspiration for a 'Win-Win': low phase noise AND low cost in a plug n' play synthesizer solution.

The Model 500S1G6 from AR is a solid-state broadband amplifier that operates over the 0.7 to 6 GHz frequency range, and is designed for applications where instantaneous bandwidth, high gain, and linearity are required. The low level of spurious signals and linearity of this device makes the 500S1G6 ideal for use as a driver amplifier in testing wireless and communication components and subsystems, and EMC testing applications.
Corry Micronics offers two new RF pin diode switches with operation in the 1 GHz to 1.1 GHz frequency range. The CMSW-SPDTR-1G-5K is a single-pole double-throw (SPDT) hermetically sealed reflective switch, while the CMTRSW-1G1R1G-2K5 is a high power transmit/receive (T/R) switch designed to be used in IFF applications.
The process of evaluating the performance of ultra-low phase noise oscillators requires phase noise test systems with lower measurement times, lower noise floor capabilities, and high reliability and repeatability of test data. As more companies are introducing general purpose phase noise analysis tools, Holzworth Instrumentation’s HA7402A was specifically designed for measuring the phase noise of high performance OCXOs, TCKOs, SAW oscillators, and frequency standards. This white paper discusses the process of using the Holzworth HA7402A Phase Noise Analyzer to quickly and efficiently evaluate high performance oscillators.
One of the most demanding measurements in the design, verification, and production of RF and microwave devices, especially in the aerospace and defense industry, is a spurious emission search with the use of spectrum analyzers. These measurements require very narrow resolution bandwidths to reach the necessary low noise, which increases measurement time. Even using extremely fast spectrum analyzers can take hours or even days to complete. This white paper reviews the basics of spurious measurements and how the parameters used can affect the detection performance. It also presents a new technique with the R&S®FSW-K50, which can be used to make spurious search faster and easier to configure.
Role Call is a new series on RF Globalnet that will look at different jobs and career paths in the RF and Microwave industry. We’ll explore what each position entails, how much you have to know, and what experience you need to get started. The first position we have explored is a consultant engineer. Andy Dearn, the Principal Consultant Engineer at Plextek RFI Ltd., let us take a peek behind the curtain, revealing everything from the most exciting aspects of his job to the mundane day-to-day activities.
Many types of modern spectrum analyzers can detect phase noise levels automatically, making phase noise measurements a task without much thought. However, it is a good idea to better understand how modern spectrum analyzers measure deviations, as well as how to optimize a spectrum analyzer’s measurements even further. This white paper discusses key aspects in determining phase noise measurements, and presents formulas and examples that may be used for simplifying measurements.

This short animation shows predicted RCS from an air traffic control radar with an aircraft flying over a wind farm, before and after the static ground clutter (returns from terrain) are filtered out. A basic filter has then been applied to remove the portions of returns with 0-Doppler (static clutter from the ground and wind turbine towers) to approximate what a radar might see after attempting to filter out objects not in motion. Although actual radars have much more sophisticated signal processing, this basic before/after animation of RCS from subsequent scans shows the problem that standard Doppler filtering would encounter when processing returns from a wind farm.
