What Is a Cross-Guide Coupler?


Quick Answer

A cross-guide coupler is a microwave component that carries microwaves along two hollow metallic forms arranged in the shape of a cross. They are a kind of waveguide, which is a device that directs microwave energy the way wires transmit conventional forms of electrical current.

Full Answer

A cross-guide coupler is a kind of waveguide. Waveguides are hollow metal cylinders or boxes that transmit electrical current. They are only useful for transmitting electricity if the electrical signal has a very high frequency, which is the case with microwave energy.

Microwave oven make use of devices known as magnetrons, which generate electrical current in the microwave range. Cross-guide couplers direct the current to the proper locations so that the machine operates effectively.
