Wi-Fi and cellular data traffic are increasing exponentially but, unless the capacity of wireless links can be increased, all that traffic is bound to lead to unacceptable bottlenecks.
An international research team including scientists from the Moscow Institute of Physics and Technology and ITMO University has proposed a way to increase the efficiency of wireless power transfer over long distances and tested it with numerical simulations and experiments.
There are many challenges associated with improving the Size, Weight, and Power (SWaP) of electronic devices, including the limitation of the physical size and assembly processes, and spectrum congestion forcing new systems to move to higher frequencies. This article addresses these issues by discussing when to use a custom MMIC in the design process.
When developing a communication datalink range, it is important to consider the ability to provide sufficient signal strength out to the intended operational range of the platform. This article discusses the options available to improve the datalink range for different applications.
Unmanned aerial systems (UAVs) are continually advancing in respect to both defense and domestic applications. The fast development pace has led to an expanding list of missions that increase the demand on systems in terms of power consumption, payload, and the ability to operate beyond line of sight safely and reliably. This article discusses the importance of Size, Weight and Power (SWaP) to missions with UAVs.
Power amplifiers generate enough heat to require a method of sinking the heat away from the device. Sometimes, the amplifying device generates heat faster than the heat sink system can pull away. This article presents the use of temperature-controlled circuitry to shut down the internal amplifier to allow the device to safely cool before turning back on.
The evolution of radar has grown steadily over the decades to its present level that employs sophisticated computerized techniques which has stimulated the development of increasingly complex components. This white paper provides a basic introduction to radar technologies and to the application of radar equipment.
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.

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.
