June 2008 RF/Microwave Technologies Advance For Military Systems Military electronics systems generally leverage the latest technologies in order to achieve performance or even tactical advantages. Although systems, such as radar and electronicwarfare (EW) platforms, are comprehensive collections of analog, digital, and RF circuits and devices, it is often the technology in a part as small as a transistor that can have an enormous impact on the overall performance of a military electronics system. For... — Jack Browne May 2008 Synthesized LO Spans 0.05 To 20.48 GHz Direct-digital synthesis (DDS) is capable of impressive frequency and amplitude switching speeds and, depending upon the bit resolution of the DDS architecture, extremely fine frequency and phase control. DDS technology is the basis for the WaveCor line of high-performance microwave signal sources from ITT Microwave Systems (Lowell, MA), notably the firm’s latest addition, the WaveCor synthesized local oscillator (SLO) model 20.0 frequency ... — Jack Browne April 2008 Rugged Cables And Connectors Can Take Abuse Microwave and optical cables and connectors currently serve a variety of industries. Yet they always have the common objective of delivering a transmission path for both highspeed digital and high-frequency analog signals. Their diverse capabilities and performance are derived from their design as well as other factors, such as materials. As it does in every industry, design follows demand. In other words, the evolution of such factors is driven... — Nancy Friedrich March 27, 2008 Working in Military Electronics? — Jack Browne March Kudos Rochester, N.Y.—Harris Corporation is providing its JTRS-approved Falcon III AN/PRC-152 handheld radios to the U.S. Army to extend the communications capabilities of soldiers serving in mountainous and urban environments. The Army is installing Falcon III AN/PRC-152 radios in Shadow 200 unmanned aerial vehicles (UAVs) as part of a relay system to significantly extend the distance communication signals can travel. The radios provide critical aerial communication links... — Dawn Hightower February GaN Devices Arm Distributed Amplifier Broadband, high-efficiency power amplifiers serve a wide range of military applications in present and future communications and navigation systems. But amplifier designers are limited in performance by the active devices available to them. Fortunately, the growing availability of wide-bandgap semiconductor devices, such as silicon carbide (SiC) and gallium nitride (GaN) transistors, is clearing the way for broadband, high-efficiency power amplifiers... — Anthony Pavio , et al. February Assemble High-Power Attenuator Systems High-power signal processing and testing requires the use of highfrequency attenuators designed to handle large signals without damage or performance degradation. Especially when working with signals exceeding 1 kW, as common in commercial broadcast and military radar systems, reliable attenuators are critical to any test system. Most attenuators on the market rely on thick or thin film resistive designs screen printed or deposited on a flat... — Dave Distler February Amplifiers Span 20 To 4000 MHz To satisfy applications ranging from point-topoint and multipoint radios to military jammers, an amplifier line boasts noise figures down to 0.9 dB. The QBH-8900 series amplifiers are available in frequencies from 20 to 4000 MHz. Second-intercept-point values range up to +75 dBm while intercepts reach +45 dBm. The QBH-8900 series from 10 to 28 dB. In addition to a lightweight, low-cost, package, no external circuitry is needed. The amplifiers, which feature internal blocking... — Nancy Friedrich January 2008 Growing SDR Market Predicted To Hit $10 Billion By 2011 NATICK, MA — The defined market for software-defined radio (SDR) is rapidly expanding. It should be noted, however, that this expansion is based largely on how the value propositions of certain SDR components or features resonate with each market segment. There are two distinct markets for SDR technology: military and commercial. The former is dominated by the United States’ Joint Tactical Radio Service (JTRS) program while the latter is driven by the deployment of upgradeable... — Jack Browne January 2008 Technology Developments Predict And Conquer Threats Although interoperable communications remains a top priority, innovations are constantly being designed to help the US recognize, combat, and recover from a terrorist attack. Homeland security continues to be a hub of research and investment activity. Going back six years ago, most development efforts seemed focused on airline safety, passenger screening, and communications interoperability. The object was to prevent a repeat of September 11, 2001. At some point,... — Nancy Friedrich January 2008 Synthesizer/Converter Brings DDS Benefits To 40 GHz This synthesizer module delivers DDS speed, accuracy, and modulation capability in bandwidths as wide as 25 percent of frequencies from 1 to 40 GHz. JASON SEIFERT Vice President of Engineering Spinnaker Microwave, Inc., 3281 Kifer Rd., Santa Clara, CA 95051; (408) 732-9828, Internet: www.spinnakermicrowave.com. Frequency synthesizers operating at microwave and... — Jack Browne November 21, 2007 November 21, 2007 Newsletter Increased Browsing Will Fuel Mobile WiMAX, Lockheed Martin Picks Phase Matrix For DTO, Tyco Adds RoHS Coaxial Connectors, TEGAM Joins LXI Consortium, Elcom Technologies Earns $3.5 Million In New Orders, Yokogawa Unleashes Wide-Range Optical Analyzer, NEE Establishes International Arm — Jack Browne November 20, 2007 Lockheed Martin Picks Phase Matrix For DTO — Jack Browne November 20, 2007 Elcom Technologies Earns $3.5 Million In New Orders — Jack Browne September 14, 2007 September 14, 2007 Newsletter Adding Talent Through Acquisition, Antenova Shrinks GPS Antenna Module, Agilent Adds Source-Corrected NF Measurements, VME Tuner Performs SIGINT Operations, LXI Consortium Gathers For Munich PlugFest, Rockwell Collins Aims GPS Receiver At Commercial Market, MITEQ Releases Control Products Catalog. — Jack Browne September 13, 2007 VME Tuner Performs SIGINT Operations — Jack Browne September 2007 Tracking Trends In Military-Electronics Technologies Military-electronics technology has long trended toward achieving more functionality and performance in smaller packages. The ways in which electronic technologies are applied may change, but that trend for smaller and lighter electronic devices and systems remains. For companies faced with supplying electronic components and equipment for military applications, most innovations focus on saving size, power, weight, and, of course, cost. At the highest... — Jack Browne July 27, 2007 July 26, 2007 Newsletter — Jack Browne July 26, 2007 TRAK Microwave Nails $4 Million Contract — Jack Browne June 2007 Innovations Lead To Multi-Pronged Homeland Defense Markets that are heavily funded often encourage the development of a breadth of products and technologies. Such is the case with today’s homeland-security market. The events of September 11, 2001 revealed just how vulnerable the United States was, and began the growth of a market based on using the latest technologies to preserve safety and freedom. From the lack of updated “sniffers” at airports to radio interoperability between different public-safety agencies, a lot of... — Nancy Friedrich  prev. page
