What Is a Microwave Coupler?
A microwave coupler is an electronic device that distributes, combines, and separates electromagnetic waves within the microwave frequency spectrum.
It operates by guiding microwave electromagnetic waves through transmission lines, such as waveguides or microstrip lines, allowing for the branching off of a specific portion of the power or the merging of multiple waves. This principle is essential for managing wave propagation and ensuring efficient power distribution.
Widely used in microwave communications, radar systems, medical diagnostics, electronic instrumentation, and automotive technologies, microwave couplers are praised for their ability to easily distribute, combine, and separate signals. Their compact and lightweight design adds to their versatility. Various types exist, categorized by coupling and separation techniques, and frequency range. Selection criteria include specific functionality needs, compatible frequency bands, and desired output power levels.
