As a leading manufacturer and supplier of RF, microwave and millimeter-wave products, many industries around the world rely on Pasternack, including avionics, military electronics, IFF, SATCOM, ECM, industrial/manufacturing and oil/gas.
Pasternack’s Voltage Standing Wave Ratio, or VSWR / return loss calculator, like our other online RF calculators, are suited for designers and engineers who require solutions for radio frequency related questions for products and designs. This is especially true during the planning and design phase of projects.
To measure how RF power is transmitted into a load, a Voltage Standing Wave Ratio will let you do so, efficiently. In an ideal situation, when connecting a power amplifier to an antenna through a transmission line, there should be no reflections, allowing all the signals to seamlessly be transmitted to the antenna. However, that is not practically possible, with some signals reflected back to the transmission line.
A VSWR calculator allows you to calculate how much of this signal is reflected back into the system. Higher the VSWR, poorer the transmission line efficiency and reflected energy.
A VSWR is the ratio of the maximum standing wave amplitude at one node to the minimum amplitude at another node in a system. In a typical RF application, VSWR is used to measure the amount of reflection due to impedance mismatch. Our VSWR impedance calculator helps find voltage standing wave ratio, return loss, mismatch loss and reflection coefficient if any one of the listed types is inputted.
Our large selection of RF calculators is part of our online technical resource library, and further complements the Engineers Resource Center section.
