Smiths Interconnect SpaceNXT Series: Elevating Space Connectivity with Pre-Tested ＆ Qualified Interconnects
Introduction
In the vast expanse of space, reliability is paramount. Whether it's
sending satellites into orbit, exploring distant planets, or conducting
groundbreaking experiments aboard the International Space Station, every
component used in space applications must withstand the harshest
conditions and function flawlessly. Smiths Interconnect recognizes the
critical importance of connectivity in the realm of space technology and
is proud to present the SpaceNXT™ Range - a groundbreaking initiative
that offers pre-tested and qualified interconnect solutions for the next
generation of space applications. In this blog, we'll take a closer
look at the SpaceNXT Series and how it is set to revolutionize the way
we connect and communicate in space.
SpaceNXT™ HC Series: Temperature Variable Attenuators
To navigate the extremes of space, we need components that can handle
temperature variations and provide precision performance. The SpaceNXT™
HC Series offers just that:
Frequency Range: Up to 18GHz, with attenuation values from 0 dB to 20 dB.
Design Flexibility: These attenuators offer a small footprint and solderable surface mount, allowing for versatile integration.
Wide Attenuation and TCA Shifts: With a wide range of attenuation
and temperature coefficient of attenuation (TCA) shifts available, these
attenuators adapt to various applications.
High Volume Solution: SpaceNXT™ HC Series is designed for
high-volume production, ensuring reliable and cost-effective solutions.
SpaceNXT™ K2TVA Thermopad® Series: Temperature Variable Attenuators for Ku-Band
For Ku-Band applications that require exceptional performance and
reliability, the SpaceNXT™ K2TVA Thermopad® Series is the ideal choice:
Frequency Range: Rated for 17-22GHz and 27-32GHz.
Robust Technology: Using a thick film process technology on an
alumina substrate, this series offers up to four times the temperature
coefficient of attenuation over the original KTVA series.
Mounting Flexibility: Various mounting configurations are available to suit your specific needs.
SpaceNXT™ MWC Series: Ku-Band Multiway Isolated Splitter
The SpaceNXT™ MWC Series is engineered for efficient signal distribution in Ku-Band applications:
Frequency Range: Operating from 10.7 to 12.8GHz.
Versatile Functionality: This isolated splitter comes in an EMC
shielded, RoHS stackable housing and can be factory-configured to
operate as either a combiner or a splitter.
Low Insertion Loss: The MWC Series offers minimal signal loss, ensuring efficient power distribution.
SpaceNXT™ Ku Series: High Power Waveguide Circulators & Loads
When power and signal integrity are non-negotiable, the SpaceNXT™ Ku Series delivers:
Guaranteed Performance: These circulators are designed for low and
stable insertion loss under maximum power, providing unmatched
reliability.
Unconditional Linearity: Tested to 350 Watts CW Power, these circulators are unconditionally linear.
EMC Compliance: SpaceNXT™ Ku Series circulators meet EMC specifications to -80 dBi, ensuring minimal interference.
SpaceNXT™ Aurora Series: ESA Qualified Backplane Connector
For critical interconnections in space systems, the SpaceNXT™ Aurora Series offers the ultimate in reliability:
ESA Qualified: These connectors are qualified to ESA ESCC 3401
specifications, assuring compatibility with the highest standards in
space technology.
Multiple Configurations: Available in 55, 110, and 125 contact sizes, as well as right angle and mezzanine configurations.
Enhanced Durability: Enhanced gold plating with 1.27µm (50 µin) increases the Mean Time Between Failures (MTBF).
SpaceNXT™ QT Series: Coaxial Cable Assemblies
In the vastness of space, signal transmission is crucial. The SpaceNXT™ QT Series ensures seamless connectivity:
High-Performance: With mode-free performance up to 50GHz, these cable assemblies guarantee uncompromised signal quality.
Stability: Thanks to phase-stable fluoropolymer dielectric,
electrical length changes are minimized over a wide temperature range.
Exceptional Shielding: With >-90dB shielding effectiveness, these cable assemblies meet NASA/ESA outgassing specifications.
Conclusion
Smiths Interconnect's SpaceNXT™ Range is ushering in a new era of
space connectivity, where pre-tested and qualified interconnects provide
reliability, performance, and peace of mind. With a comprehensive range
of interconnect solutions, space missions, and applications can now
benefit from the best in connectivity technology. By offering products
that are ready for space use, Smiths Interconnect is reducing lead
times, streamlining the integration process, and enabling groundbreaking
achievements in the cosmos. As space exploration and communication
continue to advance, the SpaceNXT™ Range stands ready to support the
future of space technology.
