SDR Forum Adding Tactical Radio SIG, Moving On Other Initiatives The Software Defined Radio (SDR) Forum is establishing a special interest group (SIG) that will focus on the needs of the worldwide tactical radio community. The Forum, a nonprofit international industry association supporting the advancement of reconfigurable wireless technology, also announced that members will vote on approval of four significant documents at the organization’s general meeting on Nov. 9... — Staff November 2, 2007 IR Receivers Feature Long Range, High Noise Immunity Designed for long-range operation in infrared remote control, data transmission, and light-barrier applications, the TSOP85 series of surface-mount infrared receiver modules targets portable systems requiring very small component profiles. — Staff November 2, 2007 LNA Boasts 20.5-dBm Gain, 0.8-dBm Noise Figure Taking advantage of the company’s advanced, low-power SiGe BiCMOS process, the MAX2659 high-gain, low-noise amplifier (LNA) from Maxim Integrated Products achieves a 20.5-dB gain and a noise figure of 0.8 dB. The device hits these performance levels while maximizing the input-referred 1-dB compression point and third-order intercept point at -12 dBm and -2 dBm, respectively. — Staff November 2, 2007 4-GHz Attenuators Suit WiMAX, WiFi, WiBro A series of broadband 2-W BNC attenuators from Coaxial Dynamics is rated from dc to 4 GHz, which includes WiMax, WiFi, and WiBro testing applications. The 6902-BNCF series offers a VSWR of 1.25:1 maximum through 4 GHz and their accuracy is ±0.3 dB to 6 dB, ±0.5 dB to 20 dB, and ±0.75 dB to 30 dB. — Staff November 2, 2007 WiMAX Measurement Solution Demonstrated At PlugFest Participants at the WiMAX Forum’s recent public Mobile WiMAX PlugFest, an interoperability showcase in Taipei, Taiwan, were able to use Agilent Technologies Inc.’s Mobile WiMAX (IEEE 802.16e-2005) measurement solutions. The company’s Mobile WiMAX testing products include the Agilent MXG, Signal Studio, MXA, 89601A Vector Signal Analyzer software, and the E6651A Mobile WiMAX Test Set. — Staff November 2, 2007 High-Performance Receive Downconverters Hit Production Volume Several single-channel and diversity downconverters from Skyworks Solutions Inc., including the SKY73032 and the SKY73021, have reached volume production with industry leading infrastructure OEMs, with more than one million units shipped. — Staff October 3, 2007 Dozens Of Products Certified To Next-Generation Wi-Fi Standard More than 95 next-generation IEEE 802.11n draft 2.0 products have been Wi-Fi Certified in the testing program’s first three months, according to the Wi-Fi Alliance. The first wave of products, from nearly 30 manufacturers, includes access points, laptop computers, routers, and wireless networking cards. — Staff October 3, 2007 Firms Cooperate On WiMAX Interoperability Testing In order to ensure that mobile WiMAX wireless products work properly together and with other products globally, Intel Corp., Nokia, and Nokia Siemens Networks have embarked on an interoperability-testing program. The program will test products across Intel’s forthcoming WiMAX silicon for laptops and mobile Internet devices, Nokia’s WiMAX devices, and Nokia Siemens Network’s WiMAX infrastructure equipment. — Staff October 3, 2007 High-Definition Digital Radios Available In Most Ford Vehicles Dealer-installed high-definition digital radios are now available as an option on nearly all 2008 model year Ford, Lincoln, and Mercury vehicles. The program makes the Ford Motor Co. the first automaker to offer HD digital radios across multiple product lines, according to the company. Additionally, HD digital radios can be installed on many earlier models from 2005, 2006, and 2007. — Staff September 7, 2007 USB Modems Support Faster HSUPA Data Speeds A pair of USB modems for High-Speed Uplink Packet Access (HSUPA) networks offer tri-band connectivity and faster data speeds to mobile broadband networks worldwide. Theoretically the modems more than five times that of current High-Speed Downlink Packet Access (HSDPA) networks at a maximum transmit speed of 2 Mbits/s. Downlink speeds are also improved with a theoretical maximum of 7.2 Mbits/s. — Staff September 7, 2007 Tiny Front-End ICs For Mobile Devices Are Highly Integrated A series of three front-end ICs (FEICs) from Anadigics Inc. come in low-profile standard packages and target space-constrained applications like next-generation, WiFi-enabled smart phones and other consumer products. The AWL9230/9231/9232 offer the industry’s highest level of GaAs on-chip integration, according to Anadigics. — Staff September 7, 2007 Single-Chip DTV Receiver Will Keep Analog TVs Going Designed to address the National Telecommunications and Information Administration’s (NTIA) digital-to-analog converter box program, the BCM3543 from Broadcom Corp. is a turnkey, digital television-on-chip with associated software. The NTIA program is intended to help extend the life of existing analog televisions by providing US residents with coupons to defray the cost of converter boxes when the FCC requires broadcasters to switch to digital broadcasts. — Staff September 7, 2007 XO/VCXO Are User-Programmable For Any Frequency From 10 MHz To 1.4 GHz The Si570 and Si571 are the first user-programmable crystal oscillator (Si570) and voltage-controlled crystal oscillator (Si571) that can support any-rate frequency synthesis, according to Silicon Laboratories. Using patented DSPLL technology and an industry-standard I²C interface, users can program either device to generate any frequency from 10 MHz to 1.4 GHz at jitter levels of 0.3 ps rms. The oscillators can be reprogrammed an unlimited number of times. — Staff September 7, 2007 L-/S-Band LNA Features Very Low Noise Figure With a noise figure of just 0.35 dB (typical) and 19 dB of associated gain at 2 GHz, NEC’s latest GaAs HJ-FET low-noise amplifier, the NE3510M04, is well suited for use as a first stage amplifier in satellite radio antenna applications. — Staff September 6, 2007 IP Network To Replace Circuit-Switch, Boost Data Rates In Handhelds The mobile phone has evolved to do much more than place a call. Common desktop applications such as e-mail access, Web browsing, and downloading music and videos are becoming common on handsets. Uploading clips to YouTube along with direct video sharing merely hint at what is to come. To do so, though, they need higher bandwidths with equally high reliability and handsets that can process such compute-intensive applications... — Jay Srage , et al. August 6, 2007 National Association of Broadcasters Engineering Handbook - 10th Edition This not-so-little jewel has 2072 pages and weighs 11 lbs. (yes, I actually weighed it). My initial reaction was that I don't have much to do with broadcast standards or technology, but after I read the book I found it was a fabulous reference on electronics, wireless, and communications in general. — Louis E. Frenzel August 3, 2007 Propagation-Analyzing Feedback Technique Boosts Wireless Transmissions Using a self-correcting feedback loop that synchronizes crystal oscillators in distant devices, a newly patented technology from Saraband Wireless Inc. considerably improves the throughput and reach of non-line-of-sight (NLOS) broadband communications. — Staff August 3, 2007 Enhanced Simulation Coverage Speeds-Up Next-Gen LTE, WiMAX Design New uplink receiver models and improved uplink/downlink source models for the Agilent 3GPP LTE Wireless Library help wireless-system designers and verification engineers speed development of 3GPP Long Term Evolution (LTE) designs for next-generation mobile communication products. — Staff August 3, 2007 Upgrades To EV-DO, HSDPA Cards Increase System Performance A pair of Mini Card Embedded Modules from Novatel Wireless Inc. deliver expanded carrier support for the next-generation of EV-DO Rev. A and HSDPA platforms and applications in development by the company’s tier-one OEM customers. Upgrades include advanced wireless functions such as antenna diversity, advanced receiver technology, increased bandwidth, and throughput of up to 7.2 Mbits/s. — Staff August 3, 2007 Highly Integrated Chip Handles Both USB Host, Device Applications Based on the WiMedia and Certified Wireless USB standards, the WSR601 single-die, digital CMOS chip integrates Ultra Wideband (UWB) PHY (including rf), MAC, and wireless USB subsystems for both host and device Wireless USB applications. The chip, from Wisair, supports HWA, DWA, and Native device protocols, and features SDIO and USB interfaces, isochronous data transfer, and cable and numeric association models. — Staff  prev. page
