Spotlight On Electronic Warfare
Electronic Warfare, Drone Wars!

Conflict is inevitable, and as a result, military force is required if a peaceful solution is unattainable. This article addresses the use of drones as a protective countermeasure in the future of military applications.

Effortless Testing Of Direction Finding Devices — Amplitude Based

Together with multiple coupled R&S SMW200A vector signal generators, the R&S Pulse Sequencer allows performance characterization of all types of direction-finding equipment such as devices that use amplitude comparison, interferometric, or time difference of arrival (TDOA) techniques. 

Designing Microwave PCBs For Successful Manufacture — Getting It Right The First Time

With improvements in processor speed and model accuracy, it is 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. 

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

A suite of software has been created that allows very fast automated analysis of some types of traveling 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.

What Is Pulse Shaping?

In this industry briefing, George Bollendorf explains a new approach to fix fidelity issues caused by the transmitting amplifier that matches input pulse signal shape, minimizes droop, overshoot, ringing, rise, and fall times.

KRYTAR Directional Coupler Primer

Directional couplers are passive devices used for sampling incident and reflected microwave power, conveniently and accurately, with minimal disturbance to the transmission line. They are used in many testing applications where power or frequency needs to be monitored, leveled, alarmed, or controlled.

Advanced LCP Substrates For HF And Microwave Applications

Micro Systems Technologies (MST) offers liquid crystal polymer (LCP), a superior organic multilayer material for substrates in RF applications with stable electrical and mechanical characteristics across a range of frequencies up to 100 GHz.
