Description
A coupler, also known as a directional coupler or coupler distributor, is a widely used microwave device in microwave systems. It distributes microwave signal power according to a specific ratio. Power transmitted on the main line is coupled to the secondary line through multiple paths, causing interference between them, while the power in the secondary line is transmitted in only one direction.
