Hermetic Feedthroughs Safeguard Mission-Critical Electronics

Experts specializing in electronics failure analysis can list a host of reasons for various malfunctions, but one of the most common causes is simple moisture. Because water and electronics do not mix well, several strategies exist to protect mission-critical components from moisture and condensation. One of the most successful methods of protecting key components from water hazards involves hermetically sealed electronics cavities—enabled by moisture-blocking component assemblies such as hermetic feedthrough technology.

IoT Drives Demand for Automotive Circuit Protection Solutions

In the past, automobiles were made up of many independent electronic systems. Even the assembly lines that were used to manufacture the vehicles required the operation and management of multiple independent systems. However, the advent of the Internet of Things (IoT) has changed automotive electronics and assembly dramatically. The connectivity that used to only be available in the home or office is now available in modern automobiles. The car itself has now become the center of communication.

Mini-Stamp as a Micro-Display for At-a-Glance Subsystem Information for DSN Links

NASA’s Jet Propulsion Laboratory, Pasadena, California Operators of the Deep Space Network (DSN) attend to numerous tasks with the overall goal of providing continuous support for the world’s deep space missions. This high-stakes operations environment requires operators to understand the state of the DSN and predict what will happen next. Under the Follow-the-Sun initiative that requires remote operations of the highly complex telecommunications equipment, operators will need to remain aware of the state of the entire network rather than just their own facility, and transition fluidly between periods of low activity and periods of high demand.

Command and Data Handling for the Magnetospheric Multiscale Mission

Goddard Space Flight Center, Greenbelt, Maryland The Magnetospheric Multiscale (MMS) mission is the fourth mission of the Solar Terrestrial Probes (STP) program. The MMS mission, consisting of four identically instrumented spacecraft, will use Earth’s magnetosphere as a laboratory to study magnetic reconnection, a fundamental plasma-physical process that taps the energy stored in a magnetic field and converts it — typically explosively — into heat and kinetic energy in the form of charged particle acceleration and largescale flows of matter.

Ka-Band Parabolic Deployable Antenna (KaPDA)

This technology provides high-data-rate communication to enable high-fidelity instruments and deep space, interplanetary missions. NASA’s Jet Propulsion Laboratory, Pasadena, California CubeSats provide the ability to conduct relatively inexpensive space missions. Over the past several years, technology and launch opportunities for CubeSats have exploded, enabling a wide variety of missions. However, as instruments become more complex and CubeSats travel deeper into space, data communication rates become an issue as highlighted by a recent NASA centennial challenge proposal. A Ka-band highgain antenna would provide a ≈100× increase of data communication rates over an S-band high-gain antenna, and a ≈10,000× increase over an X-band patch antenna of the same input power, enabling high-rate data communication from deep space or the use of dataintensive instruments from low Earth orbit (LEO).

Full-Wave Matching Circuit Optimization Shortens Design Iterations

Full-wave matching circuit optimization (FW-MCO) is a new technology introduced by Remcom, which combines full wave 3D EM simulation and circuit optimization to solve an age-old RF problem:determining which component values provide the desired match for a given matching network layout.
