dB or not dB? Everything you ever wanted to know about decibels but were afraid to ask...

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This Application Note is intended as a refresher on the subject of decibels.

SWaP-C and Why Your Component Partner Matters

The military is continually pushing to decrease the size, weight, power and cost (SWaP-C) of its electronics, particularly for items carried by the troops. To meet these goals, everyone involved in designing and manufacturing the device needs to work together closely to ensure maximum efficiency of every component. This makes choosing the right partner crucial. Our white paper explores why SWaP-C is so important and includes information on:

Neutralizing Nature: Controlling the Environment in Aerospace

If your goal is to send a billion-dollar satellite into space or to maintain precision defense systems aboard aircraft tasked with defending the nation, environmental variations aren't so much the spice of life as an endless minefield of potential hazards that could destroy your mission. In the unforgiving aerospace sector, the idea is not to celebrate nature but to neutralize it, creating artificial environments that remain precisely clean and stable, wherever the equipment or payload you're assembling, transporting and sending aloft happens to be.

2016 Create the Future Contest: Aerospace & Defense Category Winner

FLASH® BAINITE — HIGH PERFORMANCE ARMORGary Cola, Flash Bainite, Washington, MI “This award provides small-scale manufacturers, the largest steel mills, and all in between the Flash knowledge to make everyday steel components stronger than titanium, lighter than aluminum, yet able to fold almost like paper. Migrating Flash Armor Technology to civilian markets will allow automotive, agricultural, architectural, shipping, and oil/gas infrastructure to be lightweight, yet stronger.” The Flash® Bainite Process is a rapid heat treating process for creating steel that is stronger than titanium, lighter than aluminum, and made at lower cost than traditional high-strength steel. Flash Bainite steel, which was originally developed for the armor industry, is migrating to civilian uses such as automotive applications (safer/lighter crash structure), building/bridge construction (stronger), and even lawn edger blades (longer life).

Epoxy-based Hermetic Feedthroughs Boost Switchgear Reliability

With medium-voltage switchgear, progress is being made with regard to finding alternatives to SF6 as an insulation gas. Designs that incorporate dry air or a mixture of fluoroketone, nitrogen and oxygen as the insulating gas are being explored to minimize environmental impact.

Antenna Basics

The antenna is the most intrinsic component of all RF systems, yet the principles of antenna design and wave propagation are rarely discussed outside the entry level engineering classes. Rohde & Schwarz has developed an educational white paper on Antenna Basics to reteach the basic principles in a simplified manner.
