The RF engineering field is an exciting and growing industry, and different firms are always competing to attract that best talent to their teams. But finding the best new employees isn’t as simple as just posting on job boards anymore. To stand out from the crowd, engineering companies use social media to present themselves in the best light to not only their customers but to potential new recruits as well.
RF engineering is a massive and growing industry. Over the last quarter-century, it has gone from simple commercial radio, TV and military communication/detection systems to being an indispensable field of technology that is required for the global economy to function. Wi-Fi, satellite communications, 4G networks and more are all made possible by RF technology, and with exciting developments like 5G and “Space 2.0” just around the corner, the demand for skilled RF engineers is only going to increase. So, if you’re an aspiring engineer who wants to get in on the action, where do you start?
Our workforce is going through one of the biggest transformations ever. Of course, we’re talking about the retirement of the Baby Boomer generation and the rise of the Millenials. Just like every generation before it, the millennial generation requires a special approach to empower them to do their best work. To other generations, millennials have gotten a bit of a bad rep, but the truth is, they’re not bad, just different.
Fifth Generation Wireless is Right Around the Corner
Fifth generation wireless systems are not far from becoming a reality, thanks to recent research being done on the millimeter wave (mmW) radio spectrum. Experts agree the way forward is to manufacture mass deployable wireless devices across a range of markets and for different applications. Among other things, these applications include mobile computing and data processing over networks. The technology also has applications in the field of medicine and healthcare.
PSRR filtering is becoming more and more difficult for engineers to incorporate into timing designs. In this post, we explain why this is, what PSSR is in the first place, and the best ways to avoid the dreaded "supply ripple". You'll have a strong understanding of the problems and solutions that arise from PSRR by the end of this post.
It's a new day. The sun begins to rise. Birds begin to chirp. The smell of freshly brewed coffee is in the air.
