A chip has been designed at NASA's Jet Propulsion Laboratory to increase the usefulness of monolithic millimeter-wave integrated circuit (MMIC) components at submillimeter-wave frequencies. The chip incorporates two integrated, radial E-plane probes with an MMIC amplifier in between, thus creating a fully integrated waveguide module. This technique can be used in submillimeter-wave imaging in homeland security, weapons detection, and commercial test equipment. Click here.

CAD Tools: Breaking Barriers

With difficult economic times, CAD vendors are under more pressure than ever to provide customers with products that increase productivity, reduce time to market, and give them more value for their money. In our annual poll of CAD company executives, we found that new technology is the focus in helping customers break the barriers to efficient design with limited resources. Five years ago, we asked executives at leading CAD companies if, in five years, most design engineers would be using 3D design tools rather than 2D, and all of them said yes. Yet, there are still barriers that design engineers face in migrating from 2D to 3D. Jeff Ray, CEO of SolidWorks, believes one major barrier continues to be fear of change.

Connectors Provide Signal Reliability for Mars Science Laboratory

Compact PCI (cPCI) ConnectorsHypertronics CorporationHudson, MA978-568-0451www.hypertronics.com Hypertronics’ space-grade Compact PCI (cPCI) connectors were selected by NASA’s Jet Propulsion Laboratory (JPL) for use on the Mars Science Laboratory (MSL), which is scheduled to launch in 2009. Incorporating the Hypertac® “Basket of Wires” contact technology, the connectors will be instrumental in all phases of the mission including lift-off, navigation, entry, descent, landing, roaming, and geological survey. Behind these embedded systems are single-board computers connected together through common back planes that handle all control functions and analysis for the MSL rover. All systems and components must exceed the long and difficult journey to Mars, as well as the extreme surface operation of one Martian year, equal to two Earth years.
