Hittite’s HMC-C071 general purpose, broadband, non-reflective is rated for operation from DC to 20 GHz. This broadband operation combined with high isolation of >32 dB up to 20 GHz, and low insertion loss of 3.5 dB up to 20 GHz, makes
War just ain’t what it used to be. Today’s threat comes not from rival nation-states, but from stateless entities. This has fundamentally changed the nature of warfare, as the concept of “total war” has become irrelevant. If “collateral damage” is lawful, “so long as it is not excessive in light of the overall military advantage anticipated from the attack,” then urban combat necessitates a change in tactics
Hewlett-Packard Co.'s 19 percent drop in quarterly profit shows that the company still relies heavily on printer ink and the troubled personal computer market, despite the aggressive transformation it's undertaking to branch out and encroach more on rival IBM Corp.'s turf
Microsoft Corp's Bing search engine continued to make small gains on rivals Google Inc and Yahoo Inc in the U.S. Internet search market in July, according to the latest data from research firm ComScore.
NASA scientists have discovered glycine, a fundamental building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft. "Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet," said Dr. Jamie Elsila of NASA's Goddard Space Flight Center in Greenbelt, Md. "Our discovery supports the theory that some of life's ingredients formed in space and were delivered to Earth long ago by meteorite and comet impacts."
Germany launched a campaign Wednesday to put 1 million electric cars on the road by 2020, making battery research a priority as it tries to position the country as a market leader. The program, which draws on euro500 million ($705 million) set aside in an economic stimulus package earlier this year but leaves many financing details up to the next government, drew criticism for being too vague.
Boeing Co. has discovered another problem with its long-delayed 787 jetliner, prompting the aircraft maker to halt production of fuselage sections at a factory in Italy. The Chicago-based company found microscopic wrinkles in the skin of the 787's fuselage and ordered Italian supplier Alenia Aeronautica to stop making sections on June 23, spokeswoman Lori Gunter said Friday. Boeing has started patching the areas.
South Korea on Wednesday aborted its first domestic launch of a rocket just minutes before scheduled liftoff because of a technical problem, delaying space ambitions that have threatened to anger rival North Korea. The rocket was to have shot into space about four months after North Korea was widely criticized for firing its own rocket in defiance of United Nations sanctions. The North said it would keep a close eye on the international response to Seoul's rocket launch.
The LAN9303 and LAN9303M (from SMSC) are purportedly the industry’s smallest fully-integrated, 3-port 10/100 managed Ethernet switches for home networking applications. The switches include support for single/dual MII/RMII/Turbo MII (Media Independent, Reduced Media Independent and Turbo Media Independent Interfaces).
With a 7-slot skewed armature design, the Pittman “Series 8000” brush-commutated DC motors from AMETEK minimize magnetic cogging (or reluctance torque). The motors are available in three lengths (2.070 in., 2.195 in., and 2.445 in.) and can achieve peak torques up to 16.8 oz-in and speeds up to 9020 RPM at continuous torque.
Featuring an IP67 rating, the PWS-8033M handheld computer from Advantech is resistant against dirt, dust, and complete immersion in under 1.2 m of water. The computer includes an XScale PXA270 624 Mhz processor with 3.7” transflective VGA TFT LCD, GPS, 802.11 WiFi, and a built-in Bluetooth. It has an operating temperature of -20°C to 60°C
SEOUL, South Korea — North Korea said Monday it will closely watch the international response to South Korea's planned satellite launch after Pyongyang was brought before the U.N. Security Council for what it said was a similar move. South Korea is aiming to launch a satellite into space from its own soil for the first time as early as next week.
Bel Power has added 20 A, 40 A, 50 A, 60 A, and 80 A Power SIP modules to its non-isolated DC/DC converter portfolio. These Power SIP modules operate at efficiencies of up to 94 power over a wide input range of 4.5 V to 13.8 V, and wide output voltage trim range of
The United States is taking steps to counter a new delay in the arrival of swine flu vaccine, hunting factories that can get more of the precious liquid into syringes faster. Dr. Robin Robinson, who is in charge of vaccine procurement for the Department of Health and Human Services, says he's trying to bring additional manufacturing online for the packaging step that has emerged as a logjam.
