Results for tag: "Directional Coupler"

A directional coupler is an electrical switch used to couple two or more electrical circuits together. It is typically used to transfer power from one circuit to another, or to measure the power in one circuit without affecting the other. Directional couplers are commonly used in radio frequency (RF) applications, such as in cellular base stations, satellite communications, and radar systems. They are also used in fiber optic networks, where they are used to couple optical signals from one fiber to another. Directional couplers are available in a variety of configurations, including single-ended, dual-ended, and multi-ended. They can also be designed to operate at different frequencies, depending on the application. Directional couplers are typically constructed from a combination of metal and dielectric materials, such as copper, aluminum, and ceramic. Some of the companies in the directional coupler market include Anritsu, Keysight Technologies, National Instruments, and Tektronix. Show Less Read more
