What’s The Worst That Could Happen? RF Communication Disasters
The morning of December 4, 2011 began normally for the team of Air Force technicians. As they settled into their shift flying unmanned aircraft over Afghanistan, perhaps they chatted casually and swapped stories from the weekend. Very soon, however, their conversations were interrupted by shrill alarm sirens blaring from their control monitors. The video screen on the wall, which normally displayed real-time video imagery from their stealth RQ-170 drone, was now completely black. By Michael Clonts, Product Manager, RT Logic
Accurate System Level Design With Low Noise Amplifier’s BlackBox Models
System level simulations are not easy. Adding individual integrated or discrete component’s foundry/supplier kits to the system simulation adds complexity. Through Skyworks’ BlackBox model for its SKY67151-396LF LNA, which does not include any extra modeling kits, you can accurately simulate and predict small and large signal performance.

This guide contains a comprehensive overview of LTE technology and the testing issues it presents to both the engineer and the network operator. This 60-page document is an essential reference for engineers wanting to gain a better understanding of LTE.
Power Envelope Tracking For Mobile Power Amplifiers
Have you heard the story about the guy who had to recharge his 4G phone twice a day? Unfortunately, he was not happy with his phone. This story has been happening as the demand for high-speed data increases and battery capacity has not matched advances with communications technology. It’s not the battery at fault but the technology needed to power the amplifier on the phone.
A Multiphysics Approach To Magnetron And Microwave Oven Design
The magnetrons used in microwave ovens operate on the same frequency band as Wi-Fi equipment, and the radiation they release can interfere with the operation of wireless networks. This paper presents a multiphysics simulation of a magnetron using CST STUDIO SUITE®, with the aim of testing the electrical, magnetic, thermal and mechanical characteristics of a low-interference magnetron design. The simulation results are then compared to measurements made experimentally, and the two sets of results are shown to be in good agreement.
