    Novel Communications Architecture For Future Ultra-High Speed Wireless Networks

    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 Wi-Fi® 6 Revolution Wakeup Call For Your Test Strategy

    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.

An Automated Software Suite For Determining Electrical Characteristics Of Travelling Wave Tubes

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.

Design Of Rugged High Voltage Power Supplies For Use In Low Noise Multimode Radar Transmitter Sub-Systems

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.

Introduction To TMD Synthetic Aperture Radar Amplifiers

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.

Cross-Coupling Between A 3G Transmitter And A Cable Bundle

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.

    Antenna Design and Integration into Mobile Devices

    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.

    What Is Your Old Spectrum Analyzer Hiding From You?

    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!
