Coupler

Coupler is a device used to transfer energy from one signal path to another. It achieves this by establishing electromagnetic coupling between two paths. Couplers are employed for signal distribution, combining, or monitoring and find widespread use in RF and microwave systems. There are various types of couplers, including directional couplers, hybrid couplers, etc., each suitable for different application scenarios. Couplers play a crucial role in communication, radar, and antenna systems, among other fields.
