Incorporating microwave cavities in the design, SRF300/SRF303 series broadband TO-5 relays from Teledyne operate in the frequency band from DC to 6 GHz. The cavities allow operation at higher frequencies with low insertion and return loss and high isolation.
Delivering 240 W with an efficiency rating of 95 percent at full load and a PMBus interface included, Ericsson's BMR454 DC/DC converter is a wide-input range (from 36 V to 75 V) 1/8-brick module. The PMBus-compatible module can be configured as an intermediate bus converter or as a DC/DC module.
More than three dozen security and privacy advocates and researchers are asking Google to offer better data protection for users of Gmail and other Google apps and Google said on Tuesday that it is considering doing that, if it doesn't slow down the apps too much.
Virgin Media, Britain's largest provider of broadband services, has announced it will launch an unlimited music download program later this year. The company is initially partnering with Universal Music, the world's leading music company, although other labels and are expected to sign up when more details are announced.
Enabling quick assembly and accurate bond-line inspection, the color-changing Dymax 3-20794 adhesive bonds to a variety of substrates when exposed to UV-light. Utilizing See-Cure technology, the adhesive starts out blue in its uncured state and turns clear as the adhesive cures.
The word on the street today is that server maker Sun Microsystems - which is in the midst of being eaten by software giant Oracle for $5.6bn - has formally killed off the 16-core "Rock" UltraSparc-RK processor that has been in development for more than five years.
Available in versions rated from 1.5 MHz to 200 MHz, a family of programmable 3.3 Vin temperature-compensated crystal oscillators (TCXO) from Cardinal Components offer three outputs, CMOS, LVPECL, and LVDS.
Bureaucratic inefficiency and secrecy around government data have been hallmarks of our federal government since politicians wore powdered wigs. The country’s new chief information officer hopes to mutate governmental DNA in the direction of openness by releasing a massive amount of data about everything from swine flu to train schedules to the public, in a machine-readable, mashable way.
Offered in 61,800 rpm and 201,600 rpm windings of 1.9-in., high-speed motors from Koford Engineering include a vacuum compatible version, a 500-line optical encoder,
Some have predicted that crowdsourcing is the future of the marketing, advertising, and industrial design industries. The phenomenon, they argue, will accelerate creativity across a larger network.
Available in both in air- or conduction-cooled versions, the XMC-FPGA05F user-programmable FPGA XMC/PMC module incorporates the Xilinx Virtex-5 FPGA with four front-panel fiber-optic transceivers. (Alternative FPGAs, such as the LX155T, can be provided on request.) The transceivers are single- or multi-mode devices that support speeds including 2.0, 2.125, 2.5 and 3.125 Gbit/s.
Move over, silicon—it may be time to give the Valley a new name. Physicists at the Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have confirmed the existence of a type of material that could one day provide dramatically faster, more efficient computer chips.
Amazon has begun taking orders for its new Kindle DX e-reader, which is slated to begin shipping on Wednesday. The device has enough storage capacity to accommodate 3,500 books, the company said. The wireless device -- which sports a big 9.7-inch diagonal screen but is just one-third of an inch thick -- delivers instant access to magazines, newspapers and more than 285,000 books without users having to pay a monthly cellular bill. Amazon says e-books purchased for the device are delivered in less than 60 seconds over a built-in 3G wireless link that is widely available in all 50 states.
Available in 12-, 24-, and 48V output models, the PSA065 and PSA065M Series of 1U-high open-frame power supplies provide up to 65 W for applications such as telecom, data com, and industrial. Operating at more than 80% efficiency at maximum load, the 2 x 4-in. footprint supplies can tolerate temperatures from 0°C to +50°C and humidity from 5% to 95%.
Every time you swipe your credit card and wait for the transaction to be approved, sensitive data including your name and account number are ferried from store to bank through computer networks, each step a potential opening for hackers.
