Unmanned Aerial Vehicles Claim New Markets And Business
The use of unmanned aerial vehicles (UAVs) in border-security missions around the world is expanding rapidly. It will create new markets and new business opportunities—particularly for integrated capabilities guided by an operating concept and turnkey packages that include equipment, training, operations, and maintenance. The new research report from Market Intel Group LLC (MiG) titled, “Unmanned Aerial Vehicles (UAVs) for Border Security - Global Market &...  — Dawn Hightower

Component Refinements Advance Defense Systems
Microwave companies have struggled with the economy in 2009 as have most firms involved in designing and selling electronic products. But those involved with military markets have enjoyed far greater success this past year than their counterparts selling to commercial customers, due to the steady flow of business opportunities in the military electronics sector. For RF/microwave companies, opportunities with military customers begin at the system ...  — Jack Browne

Microwave Solutions Guard Against Mounting Threats
Terrorism continues to plague the US, as evidenced by the recent arrest of four men who planned to bomb synagogues in New York City. From a law-enforcement perspective, the problem with such threats is the varied forms that they take. The plan that was just foiled, while harmful and frightening, was localized. Yet the events of September 11, 2001 clearly were not. Those working in counter-terrorism must imagine every possible attack scenario and figure...  — Nancy Friedrich

Targeting Trends In Military Electronics
Military applications often push technologies to their limits. Applications such as electronic warfare (EW), radar, communications, and surveillance have made demands on RF/microwave technologies over the years, causing oscillator manufacturers to design sources with lower phase noise, and synthesizer developers to increase frequency switching speeds. Although it would be difficult to summarize the many trends in electronic technologies for...  — Jack Browne

Tracking Trends In Military IFMs And DFDs
Digital frequency discriminators (DFD) and instantaneous- frequency-measurement (IFM) receivers are still considered to be the preeminent advanced components for real-time, tactical signal identification and analysis. Widely used in many military electronics systems, they remain the essential component in a variety of applications including airborne and shipboard ESM, ground mobile ELINT collection, defense avionics, and RWR systems. DFDs and IFMs are...  — Kevin Burns

Military Electronics Firms Set To Weather Economic Storms
Business in the military electronics sector is generally steady and stable, in spite of an ever-changing landscape of suppliers. The reason for the stability could be arguable, of course, that the ultimate customers do not change, i.e., the military establishments of the world’s various governments tend to stay in business with constant requirements in the area of electronics and technology for military applications. The business landscape for...  — Jack Browne

Teamwork Provides Secure Surveillance Software Solution
Military surveillance systems are designed to make records of events of interest. But finding a particular event among one month’s worth of surveillance recordings can be challenging and time-consuming. For that reason, EchoStorm Worldwide (www.echostorm.net), a leading supplier of innovative video and sensor management solutions for military, government, and commercial applications, developed...  — Jessica Isquith

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

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

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

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

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

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

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

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

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
