Waveguide Couplers and Splitters

Smiths Interconnect supplies waveguide couplers, combiners and splitters for a variety of space, defense and air defense radar applications. These devices are designed to complement our waveguide isolators and terminations.

Features & Benefits

Our broad capability in the design and supply of waveguide hybrid and loop couplers. Smiths Interconnect has an expanding portfolio of couplers designed for a variety of radar and space based applications. These have been supplied as stand-alone products and as assemblies that integrate isolators, transitions etc. Our capability ranges from L to Ka-Band with coupler choice dependent on the application and the system considerations.

    Optical Interconnect Design Challenges in Space

    Aeronautical applications face many design challenges that are unique to their intended environment. The best practices for optical interconnect design for space applications include the use of radiation-resistant technology to defend against space radiation, the use of components and devices that are designed to operate in harsh environments, and meeting size, weight, and power (SWaP) and long-term reliability requirements. Finally, it is recommended to follow open standards like VPX and to look for solutions that comply with MIL and quality standards.
