RF CAREER GUEST COLUMNS
If we're to address subtle sexism, we don’t just need a plan for how to react; we need a plan to draw a line in the sand, so we know when it’s been crossed. Even harassers likely have challenges understanding where the line is after they’ve seen it crossed for so long without regard.
Bluetooth Low Energy 101
This two-part article will provide product designers with the information they need to develop quality Bluetooth low energy products, starting with an understanding of the standard.
RF CAREER DEVELOPMENT ARTICLES
Filter Terminology And Specifications
This guide acts as a quick reference for terms used to discuss filter technologies.
Microwave Power Dividers And Couplers Tutorial
Power dividers and couplers are straightforward passive components. To design a component with high performance, designers must give attention to design detail, design execution, and fabrication quality. This article discusses power dividers and couplers and defines related terminology.
Common Applications For Radio Frequency (RF) Filters
An RF filter permits a signal of interest to pass through while attenuating any undesired signals. This article describes the different filter shapes, or responses, when plotted in the frequency domain, defines general terms in filter utilization, and covers common types of applications that use RF filters.
The Basics Of Quadrifilar Helix Antennas
The ability to receive or transmit a tight beam of circularly polarized radiation while minimizing unwanted radiation is imperative to good communication. For such applications, the axial-mode quadrifilar helical antenna provides high performance and a robust platform, both in space and on the ground.
