September 2008 Blurring The Lines Between Video Games And Battle Simulators The “affordable Army” of the future—in contrast to the invested expense of the US Army’s Future Combat Systems (FCS) program—will depend upon a greater use of technologies developed for commercial pro t and adapted to military applications. Commonly known as commercial-off-the-shelf (COTS) products, and by some companies as the more rugged-sounding military-off-the-shelf (MOTS) products, hardware and software sold as COTS (or MOTS) quality implies that it is “good... — Jack Browne September 2008 Tracking The Technologies That Are Forging Future Systems Electronic technologies can provide a tactical edge in critical military systems, such as communications, electronic countermeasures, electronic-warfare (EW), and radar systems. The fundamental techniques used in some platforms, such as communications systems, undergo gradual, evolutionary progress in terms of better receiver noise figures, more robust solid-state transmitters, and more efficient modulation formats. But the changes being made in other ... — Jack Browne September 2008 Fitting Commercial Goods To Military Requirements Almost a decade ago, the United States Department of Defense (DoD) came to the conclusion that investing in electronic technologies for military applications alone was an expensive proposition. At the same time, healthy investments by electronics manufacturers to complete in the commercial sector were having little impact on the performance of military electronic systems. The solution was to use more commercial hardware and software in military system ... — Jack Browne September 2008 Products Gate-Drive MOSFETs Are Rad-Hardened The RAD-Hard line of Logic Level gate drive power MOSFETs has been expanded with the addition of 60-, 100-, and 250-V MOSFETs that are suitable for switch-mode power supplies (SMPS), satellite power distribution systems, and resonant power converters in highreliability applications. In contrast to bipolar devices, these MOSFETs can be driven directly from CMOS and TTL-level logic circuitry, simplifying many... — Jack Browne September 2008 Technology Critical To Modern Warfare Laser weapons are among the advanced technologies being incorporated into next-generation weapons systems. In addition, dynamically guided missile systems, unmanned ground vehicles (UGVs), and unmanned aerial vehicles (UAVs) will take part in a not-so-distant future battlefield where opposing forces will ultimately try to save soldiers’ lives by squaring off against each other’s technologies. For example, Northrop Grumman (... — Jack Browne 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.
