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

Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
