👉 In electrical engineering, a coupler is a component that allows two signals to be transmitted in parallel. It can be used to simplify the design of electronic circuits by eliminating the need for separate transistors or diodes. There are many types of couplers, including common-mode couplers, voltage-controlled couplers, and phase-coiled couplers. Common-mode couplers allow signals to flow in either direction without any additional components, while voltage-controlled couplers can control the signal's voltage amplitude.
