Waveguide Cross Couplers
Carolina Microwave Associates, Inc. is pleased to manufacture the following Waveguide Cross Couplers for your project success. We are able to customize to your requirements (attenuation, frequency, length, materials, power, etc..).
The cross directional coupler is a special type of directional coupler. Thus, it makes sense to follow with a general explanation applicable to the function of all types of waveguide couplers and their most important parameters. An (unconnected) waveguide coupler is a reciprocal four-port, which is also ideally loss-free. If a wave is fed exclusively into port 1, its effective power P1 is distributed to port 2 (primary path) and port 4 (coupling path). If the power exiting port 4 amounts to k2P1, then the power must be (1 – k2) P1 at port 2 because of the lossless property of waveguide port 2 (conservation of energy). Ideally there is no power exiting port 3, i.e. it is “decoupled” (isolation path). If, on the other hand, a wave is fed into port 2, port 4 is decoupled and the power fed is distributed to port 1 (primary path) and port 3 (coupling path). The magnitude of k (coupling coefficient) can vary in amplitude depending on the design of the directional coupler.
