In a industry microwave system, it is often necessary to divide the microwave power of one channel into several channels in proportion, which is the problem of power distribution. The components that implement this function are called Industrial Microwave Coupler.
Industrial Microwave Coupler are commonly used for microwave measurements, power sampling, and frequency monitoring. It has the characteristics of small size, low standing wave ratio, low frequency response and large waveguide bandwidth.
