Smiths Interconnect expands its D-Sub connector series for space, military and aerospace applications
S
miths Interconnect, provider of technically differentiated electronic components, subsystems, microwave
and radio frequency products, announced the introduction of the split pair quadrax contact technology to its rugged D-Sub connector Series.
The split pair quadrax is the next
generation contact that provides robust high-speed performance compatible with existing qualified rugged D-Sub connectors. Existing twinax contacts support data
rates of above 10 Gbps, but this performance is typically achieved at the cost of signal density in the architecture. Smiths Interconnect has designed a solution that isolates the individual pairs within the quadrax format in existing, space qualified, interconnect systems. The resulting isolated pair contact fits within existing housings and supports high density data rates exceeding 10 Gbps. The Rugged D-Sub connectors with
split pair quadrax contacts support all mechanical and environmental performance parameters with enhanced electrical signal integrity. The innovative isolated pair contact system is an ideal solution with individual twinax pairs within the quadrax format through the cable and contact. The new extended range meets the
high-speed application requirements of the Space and Mil/Aero markets. These demands include the ability to reliably transmit and receive 10 Gbps and beyond with a stable characteristic impedance of 100 and compliance to all MIL-STD-202 requirements for shock and vibration. “Smiths Interconnect’s rugged, reliable and high-performance solution is ideal for
applications requiring high speed data transfer under extreme environmental exposure,” said Paul Harris, VP sales and marketing. “The reverse gender, high speed performance quadrax contacts provide a stable, optimised impedance for signal integrity and are key additions to our product portfolio delivering a competitive edge to our customers.” In other news, Smiths Interconnect has
launched the SpaceNXTTM Ku Series of high power WR75 circulators and loads. The newly released Ku-Band family of passive waveguide components is part of an overarching 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. The SpaceNXTTM Ku Series of
Circulators and Loads is 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 12.75 GHz. 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 aluminum housing with chromate finish. “The SpaceNXTTM 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 Harris. “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.” Smiths Interconnect is well equipped
with the design experience, analysis tools and test equipment to qualify and produce flight-tested products that demonstrate compliance with customer requirements and national space agency standards.
