SpaceNXT™ Ku Series

The SpaceNXT™ Ku-Band High Power family of passive waveguide components are part of Smiths Interconnect’s overarching initiative to create a broad range of readily accessible space qualified waveguide Isolators, Circulators, Terminations, transitions, Hybrids and couplers operating in assigned bands from X to V-Band specifically for space applications.

SpaceNXT™ MWC Series

The SpaceNXT™ MWC Series is a high reliable 2-way Ku-Band isolated splitter, specifically designed and tested for space applications from MEO/GEO satellites to deep space probes.

Waveguide Couplers and Splitters

Smiths Interconnect supplies waveguide directional and non-directional couplers, combiners, and splitters for a variety of space, defense, and air defense radar applications. These devices operate in assigned bands and can be supplied as components or as passive systems integrated with other passive components.

MW Isolators & Circulators

Smiths Interconnect offers a wide range of RF/Microwave isolators, circulators and iso-adapters supplied with stripline (drop-in), coaxial, microstrip, surface mount, waveguide and combination interfaces. Devices are available from UHF to E-Band and designed specifically for their intended application power handling and operating environment.

MW Transitions and Iso-adapters

Waveguide iso-adapters span from S to Ka-Band and include coaxial and waveguide isolators with transitions to waveguide and integrated assemblies including filtering and waveguide windows. Lowest mass waveguide iso-adapter solutions are normally realised by integrating a coaxial isolator with a waveguide transition while waveguide isolators integrated with coaxial transition generally offer a superior electrical performance.

MW Waveguide Loads

Smiths Interconnect supplies waveguide loads and terminations for a variety of applications and environments including medical, space, defense, and commercial applications and are generally available from L to E-Band optimized to handle an appropriate amount of RF power. These devices complement our other range of ferrite circulators and are routinely supplied integrated into our comprehensive range of ferrite isolators.

MW Waveguide to Coaxial Transitions

Smiths Interconnect offers a wide range of transitions and iso-adapters (a transition integrated with either a coaxial or waveguide isolator. Devices are available from S to E-Band and designed specifically for their intended application power handling and operating environment.
