Waveguide Couplers

Waveguide couplers are devices used in microwave and RF technology to extract a portion of the electromagnetic power from a waveguide for analysis, measurement, or signal routing without disrupting the main signal flow. They are essential for signal distribution, sampling, and directional coupling in various applications, including telecommunications, radar systems, and satellite communications, ensuring precise signal management and system optimization.

Dolph Microwave Waveguide Couplers are meticulously designed to facilitate the distribution of electromagnetic energy in waveguide systems, ensuring efficient transfer between two pathways. Ideal for applications requiring precise signal management, such as power monitoring, interference control, and coupling, these couplers stand out for their precision, reliability, and customizable features.
