Semi-Rigid Cable Assemblies

Space Qualified Cables

Semi-Rigid space qualified cables are available with a copper or aluminum jacket, available with a selection of different platings and 4 different diameters:(.047”, .085”, .141” & .250”). High frequency RF cable assemblies are available with a wide variety of flexible and semi-rigid cable types with space orbit qualifications and are well-suited for Satellite Payloads (GEO/MEO and LEO constellations), Deep Space Probes, Ground Antenna Networks and Space Robotic Systems.

Overview

The Conformable® or hand formable (BJ - Braided Jacket), has a tin filled braid with a metal foil underlay and is also available in the same diameters as the Semi-Rigid type. Semi-Rigid .047 diameter Semi-Rigid cable is often used as an interconnect without connectors. The exposed center conductor and outer jacket are soldered directly to the circuits being connected.

Several subminiature connectors also mate well with this diameter and are used where space is at a premium and high loss can be tolerated. Semi-Rigid RG405 .086 diameter is the most common size Semi-Rigid cable. This size matches well with miniature high frequency connectors such as 2.4mm and SMP. The use of an aluminum jacket will allow final shaping at the installation site. Smiths Interconnect cable assemblies are Space Qualified and available unbent or shaped to your specifications. Semi-Rigid AL085 086 diameter is the most common size Semi-Rigid cable. This size matches well with miniature high frequency connectors such as 2.4mm and SMP.

The use of an aluminum jacket will allow final shaping at the installation site. Our cable assemblies are Space Qualified and available unbent or shaped to your specifications. 141 Size Family The .141" size is the most popular due to the improved insertion loss over the .085" sized products. The .141" cable offers a good match with most connector types and the .036" diameter center cable conductor can be used as the center pin of an SMA plug type connector with the semi-rigid and conformable versions. These features allow for mode free performance up to 35 GHz

    Taking the Fast Bridge between Neural Networks

    Neural networks have been around since the 1950s. The advent of fast, massively parallel processors like the Graphics Processing Unit (GPU) have made neural network applications like object recognition feasible. Neural networks are one means used to create Artificial Intelligence (AI). The latest iPhones now have an AI chip, primarily to offload face recognition tasks.1 Voice translation tasks would also benefit from an AI chip. Google provides voice translation as long as there is access to a cloud. The ability to translate directly from a phone without requiring Internet access to Google engines would be advantageous, and it’s possible that the iPhone is headed in that direction.
