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.
An international team of astronomers has captured the first-ever polarized radio waves from a distant cosmic explosion.
Constellation diagrams are 2D graphical representations of digitally modulated signals. They are used for the display and analysis of digitally modulated waveforms and provide valuable insight into the performance of a digital communication system.
As the number of antennas grow in wireless systems, test complexity also increases. As a result, it is necessary to generate multiple RF channels for receiver testing and to analyze multiple RF channels for transmitter testing. Generating and analyzing multiple synchronized RF signals are potentially challenging. This white paper discusses test signal requirements for the evaluation of multi-channel RF systems and how to configure instruments for these test requirements.
The U.S. and several NATO countries have been working on the seemingly impossible task of reducing size and weight of soldiers’ equipment while simultaneously increasing functionality and power. For engineers dealing with connectivity issues, this has brought about smaller and smaller connectors, cables and devices. Interconnected and portable devices have until now mainly been used by soldiers on covert operations. A wired tactical vest extends the concept of wearables beyond special forces by making the garments more modular, more accessible, and more affordable.
NewSpace networks and terminal vendors need to thoroughly test wireless communication systems and components to ensure uninterrupted operation and high quality of service. This white paper focuses primarily on the challenges ground terminals (user terminals and gateway terminals) present to design verification testing and manufacturing. Conducted and radiated test solutions are also discussed.
With improvements in processor speed and model accuracy, it is more and more common for microwave circuit simulations to bear close approximation to their eventual real-world performance. However, not all pitfalls present in the successful manufacture of a complex microwave circuit are captured in simulations. This white paper looks at some common mistakes and discusses how to adjust a design to avoid them.
MegaPhase has designed standard and unique high performance connectors and adapters. We offer a wide variety of standard connectors some of which include SMA, TNC, BNC, 2.4mm, 2.92mm, 3.5mm, 1.85mm, Type N and many more. In addition to the standard designs MegaPhase offers unique designs including our ZMA and ZN connectors for a quick disconnect bayonet style coupling these connectors offer RF keying if desired. We have designed standard straight and right angle adapters with in-series and between-series connectors. Applications include defense and commercial uses, and they are ideal for Probe Station Testing through 50 GHz. Our adapters feature linear phase slope, low SWR, and high reliability. When standard off the shelf RF connectors don’t meet your needs, our Engineering staff works with you to design interconnect products to meet your requirements, or re-engineer obsolete connectors. MegaPhase will provide excellent interconnect products that will allow you to focus on other aspects of your system design. The quality of these products is derived from our engineering staff’s years of experience in the design of custom connectors serving Defense, Commercial, and Aerospace Customers.

Within infrastructure, higher frequency ranges are increasing the size of the 5G network footprint. Can you keep up? This video introduces Qorvo’s solutions.
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!
