COTS in Space: The Radiation Barrier


COTS in space: the radiation barrier May 16, 2018 By Dan Friedlander Retired following 44 years in component engineering The road from the use of space/military electrical, electronic, and electromechanical (EEE) components in space applications to the use of commercial off-the-shelf (COTS) components in space applications is not smooth. Several barriers must be overcome, including: fear of risk, resistance to change, storage, obsolescence, counterfeits, and lead-free barriers. These manmade barriers were challenges also encountered by military users during the successful transition to the use of COTS components in military applications. The main natural space environmental barrier to be overcome is the radiation […]

Marines Want Armored Recon Prototypes By 2023


Marines Want Armored Recon Prototypes By 2023: F-35 On Wheels Or FCS Redux? By SYDNEY J. FREEDBERG JR. WASHINGTON: By 2023, the Marine Corps wants prototypes for a radically new scout unit they want to be the ground version of the F-3F-35 5 — scouting ahead into hostile territory, killing key targets, and feeding data back to the rest of the force. Though called the Armored Reconnaissance Vehicle, the project has evolved well beyond a straightforward replacement for the aging Light Armored Vehicle (LAV) into a networked family of manned vehicles, ground robots, and drones, collectively capable of not only reconnaissance but also electronic warfare and long-range precision strikes. Marine […]

Conference on Millimeter and Terahertz Waves


The 2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2018), Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2018) held from 9th to 14th, September, 2018 in Nagoya Congress Center, Nagoya, Japan. The conference offers an excellent chance for interaction among participants, as well as the companies providing hardware, software, services, etc. on sciences and technologies of IRMMW-THz and related products. Based on the statistics of the past IRMMW-THz conferences, hundreds of researchers in this field are expected to participate. We strongly encourage the companies to be a sponsor or an exhibitor, an indispensable part of the conference, to […]

Pentek Quartz board taps Xilinx RFSoC FPGA


Pentek Quartz board taps Xilinx RFSoC FPGA to enhance resource integration, connectivity for radar, EW, DRFM May 21, 2018 By Courtney E. Howard  Chief Editor, Intelligent Aerospace UPPER SADDLE RIVER, N.J. Pentek Inc. in Upper Saddle River, New Jersey, is introducing the first product in its Quartz Architecture family: the Model 5950 eight-channel A/D and D/A converter, 3U OpenVPX board based on the Xilinx Zynq UltraScale+ radio-frequency system on chip (RFSoC) field-programmable gate array (FPGA). The low-latency benefits of the Quartz architecture support digital RF memory (DRFM) and radar applications that were previously not possible with earlier generation products, officials say. “The Zynq Ultrascale+ RFSoC FPGA […]

Lockheed Martin selects BAE Systems


Lockheed Martin selects BAE Systems to sustain F-35 electronic warfare systems By Courtney E. Howard  Chief Editor, Intelligent Aerospace NASHUA, N.H. Lockheed Martin officials in Bethesda, Maryland, needed a trusted industry partner to help ensure the readiness of critical electronic warfare (EW) systems on the company’s F-35 Lightning II military fighter aircraft. BAE Systems in Nashua, New Hampshire, won a five-year contract to manage the supply chain and establish the infrastructure necessary to keep systems mission-capable and readily available to warfighters. The EW suite for the F-35, called the AN/ASQ-239 system, provides the pilot with situational awareness and protects the aircraft with advanced […]

Massive-MIMO Hybrid Beamforming


Algorithms to Antenna: Massive-MIMO Hybrid Beamforming Hybrid beamforming can be a practical option when it comes to massive-MIMO systems. This post examines the technology and the techniques employed for both multi-user and single-user systems. Rick Gentile I would like to build on my previous blog discussions related to hybrid beamforming, but this time I will look at how hybrid beamforming can be implemented in a massive-MIMO system. To start with, I will focus on hybrid beamforming at the transmit end of a massive-MIMO communications system, including techniques for both multi-user and single-user systems. We can then partition the resulting precoding […]

DOD wants drones to deliver blood


DOD wants drones to deliver blood on the battlefield BY ADAM MAZMANIAN Battlefield drones typically deliver weapons or spy out enemy positions. Now the U.S. military is looking for ideas on how to deliver blood and medical products to remote locations to treat wounded troops on the spot. The specs of the solicitation from the Defense Innovation Unit Experimental — the ability to deliver a 5-pound package over 100 kilometers in “austere environments” — strongly suggest that they’re looking at an unmanned aerial vehicle system that supports refrigeration or other means of temperature control. “These deliveries, ideally automated, will provide […]

Wireless Bandpass Filters – Metamaterials


MATERIALS Wireless Bandpass Filters Build on Metamaterials These second- and third-order bandpass filters leverage metamaterial resonators for low passband insertion loss and high out-of-band rejection for wireless applications at 2.4 GHz. Ahmed A. Ibrahim, Mahmoud A. Abdalla, Adel B. Abdel-Rahman 1 | May 18, 2018 Download this article in PDF format. Microwave bandpass filters (BPFs) are essential for maintaining separate channels in wireless communications systems. As such systems become more compact, BPFs must meet more demanding requirements for smaller size, lower insertion loss, higher out-of-band rejection (selectivity), and lower cost. Several techniques are used to design microwave BPFs,1-4 although the authors have developed an approach […]
