Guide to Understanding and Developing an RF Switch Network


Welcome to the Guide to Understanding and Developing an RF Switch Network, an accumulation of insightful content that arms you with the necessary knowledge to design your RF switch network. This five part document begins by explaining basic RF switch specifications such as insertion loss, VSWR, characteristic impedance, and rise time. It then discuss the importance of switch system design by explaining how choosing the right topology for your application can increase its performance incrementally. The third part of this guide provides you with an overview of the smaller but equally important components that form a part of the switch network, such as cables, and connectors. The fourth part highlights the importance of impedance matching in RF systems using graphs and circuit diagram analysis. Finally, this series of tutorials culminate with a tutorial that discusses the process of picking components and designing an actual RF switch network for optimal performance.
