This new series of ultraminiature relays are designed to attenuate RF signals in 50 and 75 systems over a range from dc to 5 GHz. They have a low profile and small grid spacing, measuring .375 x .510 x .295 inches (9.53 x 12.96 x 9.49 mm), and only weighing .11 oz (3.2g). Leads measure a minimum of 0.7 inches (17.78 mm). The relays have a normally closed low-toss, bypass path and an attenuation path. The single-section relays have an internal matched thin film attenuator pad in a "Pi" configuration. They come in a fixed 20 dB attenuation value, but other values in a range of 1-16 dB are available upon request. They have a high repeatability (+/- 0.1db), high electrostatic discharge resistance, a uni-frame motor design for magnetic efficiency and mechanical rigidity, and gold-plated, precious metal contacts. Price is $35.44 each in 500-unit quantities. Teledyne Relayshttp://rbi.ims.ca/4928-597
A next-generation guided ammunition system for intercepting enemy fire that Lockheed Martin is developing for the Army has hit its targets in an initial series of tests by the company.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
