3.3V mixer downconverts RF with good linearity 10/28/2009
Linear Technology Corp’s new LTC5541 downconverting mixer operates at frequencies of 1.3 to 2.3 GHz, and the company plans to later introduce pin-compatible parts that will operate at 0.6 to 4 GHz.Device enables remote computer control and management 10/16/2009
IT support for computers in remote locations, which include areas as diverse as test equipment, desktop applications, and shopping-center kiosks, often requires the ability to take control of the application’s computer over the Internet while maintaining a secure environment.Cyborg crickets could create cooperative community networks 8/6/2009
Crickets, cicadas, katydids, and some other insects make noise by beating their wings. More significantly, they can change the pitch of their wing beats and, hence, the frequency of the noise in response to changes in pitch of other nearby insects.Cascade Microtech addresses power semiconductors and RFICs 7/8/2009
Cascade Microtech is addressing the emerging energy-efficiency standards that are driving the need for accurate power-device characterization in automotive, mobile-device, transportation, and other applications.Agilent, ETS-Lindgren address A-GPS test 6/11/2009
Agilent Technologies Inc has introduced GS-9000 A-GPS (assisted-global-positioning-system) test systems employing the company's 8960 wireless-communications-test set's new A-GPS-assistance-data-messaging-test capabilities.EDN names winners of 19th Annual Innovation Awards 3/31/2009
EDN has bestowed its 19th Annual Innovation Awards, honoring a diverse group of electronics engineers and the ground-breaking products they have produced. The Altera Stratix IV 40-nm FPGA design team is named Innovator of the Year. Read on for a complete list of the winners.Researchers advance quantum-memory-retention time 2/5/2009
Researchers at the Georgia Institute of Technology have announced a significant advance in the retention time of multiatom quantum-memory devices—from a previous maximum of 32 msec to 7 msec. The significance of the advance is that, with retention time of milliseconds, a bit in quantum memory now lasts longer than the time it would take a photon to travel through 100 km of optical fiber f...IBM claims graphene field-effect transistors at GHz frequencies 12/19/2008
With a top-gate design and a gate length 150 nm, IBM achieved a cut-off frequency of 26 GHz for its graphene transistors.Tzero promises demo of 1080p60 wireless HDMI using UWB 12/3/2008
UWB (ultrawideband) silicon provider Tzero Technologies today announced that it plans to demonstrate at a developer's conference in Japan this week a "commercially viable" UWB implementation capable of delivering a 1080-line, 60-frame/sec HDTV signal.Consolidation among mobile-IC makers squeezes supply chain 11/13/2008
Continuing the considerable consolidation in the mobile-IC supply chain, Freescale Semiconductor announced a planned exit from the cellular-handset-chip-set market. The company in October said that it is exploring its options for the business, including the unit’s sale or the formation of a joint venture, just weeks after STMicroelectronicsPower-stingy digital accelerometers yield benefits in gesture-driven consumer devices 11/6/2008
Features involving a device’s motion, such as a tap-to-mute capability on a cell phone or a user-input feature on a gaming controller, can serve as communication tools.POE devices cater to higher-powered applications 10/16/2008
Manufacturers of PDs (powered devices) that rely on the IEEE 802.3af POE (power-over-Ethernet) standard rather than ac wall power can shrink board space and the BOM (bill-of-materials) costs.PicoChip optimizes processor-array chips for femtocells 9/18/2008
PicoChip’s second-generation PC3xx family devices integrate the company’s modem architecture in a form that will increase performance and reduce the bill-of-materials cost for femtocell manufacturers. The first of the new family, the single-chip PC302, for HSPA (high-speed-packet-access) femtocells complies with the TR25.FPGA IP completes wireless-backhaul method 8/21/2008
Wintegra’s third-generation UFE3 (universal-front-end-3) IP (intellectual-property) core for high-channel-density, wireless-backhaul designs provides an upgrade path for designers migrating voice-centric cellular systems to high-capacity data-plus-voice-capable designs. The core works with the company’s WinPath2 processor and PMC-Sierra’s Temux family of framers and mappers.Photonics researchers decelerate light to accelerate data 8/21/2008
A research team at the USC (University of Southern California) Viterbi School of Engineering has received $4.3 million in DARPA (Defense Advanced Research Projects Agency) funding to develop continuously tunable optical delays, which could accomplish tasks such as multiplexing entirely in the photonic domain—without the inefficient conversion of light streams into electronic signals and b...ADVERTISEMENT
