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
VNAs With Wide Frequency Coverage Help Overcome High-Speed Interconnect Challenges
Cloud computing, smartphones, and LTE services are creating a significant increase in network traffic. To support this added traffic, speed of IT equipment – such as those used in high-end services in data centers – must be increased, creating challenges for signal integrity engineers that must be met by advanced test instruments, such as vector network analyzers (VNAs).

RF Switch Matrix Basics: Configuring And Verifying With Simulation Tools
RF and microwave switch matrix solutions play a key role in a variety of test systems. At SenarioTek, we design and configure signal routing solutions that are often unique to a specific application. Over the years, we have found some basic steps that help facilitate the design process and ensure that the finished product meets the needs of the test system. This column covers what I believe are the most important initial steps in the process. This is the first in a series of guest columns by Bob Alman of SenarioTek.
Transitioning Designs To Manufacturing: Partnering For Success
Innovation and the development of new products are critical to the overall success of most companies. Leading companies have a continuous pipeline of new technology and/or product development and the process discipline in place to transition new developments into manufacturing. Product development is typically resource-intensive, involving investments in labor, materials, and capital. High frequency products as well as other leading-edge technology-based systems pose unique challenges to successful product development and manufacturing. In order to maximize success and optimize the returns on these investments, it’s imperative to employ a disciplined and comprehensive process from the design phase through the transition into manufacturing and throughout the product’s lifecycle.

Analyzing Frequency Response Of Inertial MEMS In Stabilization Systems
UAV-mounted surveillance equipment, maritime microwave receivers, vehicle-mounted infrared imaging sensors, and similar instrument systems require stable platforms for best performance, but they are often used in applications that experience vibration and other undesirable kinds of motion. Vibration and normal vehicular movements cause communication loss, blurry images, and many other behaviors that degrade the instrument’s performance and ability to perform its desired function. Platform stabilization systems employ closed-loop control systems to actively cancel this type of motion, thus preserving mission-critical performance objectives for these instruments.

LS Research Announces The Opening Of The Antenna Shop, Providing Dedicated Specialists To Ensure An Optimized Antenna Design For Wireless RF Devices
One of the most important – and overlooked – components of any RF device is the Antenna. An improperly designed antenna can greatly impact radio performance and be very costly to a device manufacturer as Apple discovered shortly after releasing the iPhone 4. Its improperly designed antenna ultimately cost the company $53 million.
