What is the voltage standing wave ratio (VSWR) in RF systems?
Voltage Standing Wave Ratio (VSWR) is a fundamental parameter that measures the efficiency of radio frequency (RF) power transmission from a source through a transmission line to a load. A simple way to measure VSWR is to find the highest to lowest voltage ratio in a standing wave created on a transmission line due to […]

When reality intrudes on component models and equivalent circuits
Determining the utility of an equivalent-circuit model versus construction reality is often a difficult challenge. Using simplified, first-order approximations in models and equivalent circuits is a normal part of engineering life. Without them, we would get mired in the details and harsh reality of the components and their characteristics. We would never be able to […]
