An international team of astronomers has captured the first-ever polarized radio waves from a distant cosmic explosion.
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 with optical fiber.
The IEEE 802.11ax amendment (Wi-Fi 6) focusses on greater efficiency in wireless connectivity. While the key attributes of this improved efficiency directly improve traditional Wi-Fi applications, the attributes will largely affect higher-density applications such as large offices, shopping malls, apartment complexes, airports, indoor arenas, outdoor stadiums. This white paper offers several ideas of how to make Wi-Fi 6 a reality.
Travelling wave tubes are vacuum devices with electron beams that couple to a microwave frequency electromagnetic signal propagating in the direction of the beam. Energy is transferred to the microwave signal, and the device generally behaves as an amplifier. A suite of software has been created, which allows very fast automated analysis of some types of travelling wave tube. This white paper delves into the design and use of this software to be used for determining the electrical characteristics of traveling wave tubes.
A radar transmitter is generally required to amplify a low noise coherent RF waveform. This waveform is generally provided by a radar RF exciter and can be fixed frequency, frequency chirped, or phase modulated during the radar transmitter pulse. It is important that the transmitter system amplifies this pulsed signal to a high power whilst maintaining its coherence and its fidelity. This paper covers an approach to the design of high voltage power supply units for operating traveling wave tube amplifiers in pulse doppler radar transmitter sub‐systems where ultra-low noise RF output is mandatory.
Amplifiers for Synthetic Aperture Radars (SAR) or Imaging Radar, although evolved from general purpose radar transmitters, have special requirements associated with the application where it is used. TMD has been involved with ISAR, SAR, and GMTI since their inception in the early 1990s and have a reliable track record of reliable supply and operation performance.
This white paper explains how to compute cross-coupling effects between a cable bundle and 3G antenna mounted on a vehicle through the utilization of the cable modeling interface in FEKO. It also demonstrates the FEKO GUI elements that are useful for setting up an investigation into the cross-coupling between transmitters and cable bundles.
To comply with the new International Fire Code and National Fire Protection Association (IFC/NFPA) standards, the Bird RescueLine delivers on a key objective: ensuring that first responders have reliable radio communications in large structures...
FEKO, Altair’s comprehensive electromagnetic simulation software suite, can be used in electronic virtual prototyping and simulation driven designs, including antenna design for many products such as mobile phones, tablets, cameras, laptops, and TVs. The software can eliminate weak antenna designs and reduce the number of prototypes with its proof of concept and comparative studies. Pre-compliance of over-the-air (OTA) radiation performance and specific absorption rate (SAR) can be estimated for the standalone device, or for different usage environments.

Our engineer takes you into the features, benefits and markets for the new AR-5010 amplifier. The AR-5010 is a class A amplifier designed with optimized performance to support linearly modulated, multi-carrier waveforms with high crest factors. The AR-5010 is a part of AR Modular RF’s AR-5000 Series which is the next generation of wide-band, Class A/AB linear amplifier designed for use with modern digital modulations.
Digital Phosphorus Technology, or DPX, is a Tektronix patented acquisition mode that performs the hardware DSP processing and rasterizing of the samples into pixel information in order to reveal a greater amount of signal detail. It gives a truly “live” view of the RF signals, with its color-grading feature allowing users to see different signals at the same frequency yet separated by either time or power levels. In this video, DPX is demonstrated and reveals signals that your old spectrum analyzer might be hiding from you. You can literally see signals hidden beneath other signals!
