An initiative to create a broad range of readily accessible space-qualified waveguide isolators, circulators, terminations, transitions, hybrids and couplers operating within assigned frequency bands from X to V-Band has commenced at Smiths Interconnect with the release of the SpaceNXT Ku Series of high power WR75 circulators and loads.

These Circulators and Loads are specifically designed for MEO/GEO satellites and offered with recognised testing sequences in order to reduce delivery times and overall cost of ownership. Testing is performed in compliance with general space qualification flow, incorporating industry standard power and environmental requirements.

The Ku Series currently consists of the WR75 model covering key performance characteristics at frequency bands from 10.7 to 12.75GHz. The devices demonstrate low and stable insertion loss characteristics under maximum power.

They are well sealed for electromagnetic compatibility (EMC) and constructed with a low-mass aluminium housing with chromate finish.

“The SpaceNXT Ku Series circulators provide our customers with a combination of highly reliable technology and lower cost of ownership, benefitting from Smiths Interconnect’s overall design expertise gained from over 40 years of space heritage”, says Paul Harris, VP of Sales & Marketing. “With the SpaceNXT initiative we are creating a more streamlined purchasing experience by shifting the product testing responsibility from the customer to us. With the Ku Series we are reaching new heights in operating frequency and bandwidth, enabling our customers to achieve compelling milestones in a growing market.”
