AOC VIRTUAL SERIES: Wideband Frequency Conversion and Characterization, February 2

Thursday, February 2, 14:00-15:00 EST | 19:00-20:00 UTC

The frequency converter is a key component in heterodyne systems including radars, communication systems, and EW systems. Advanced electronic systems utilize wide instantaneous bandwidth and wide tuning bandwidth for several reasons. In radar, bandwidth translates into range resolution, while in communications applications, bandwidth is related to symbol data rate. Electronic warfare (EW) deals with either protecting, disrupting or intercepting these radar or communications functions. For example, LPI waveforms utilize wide bandwidth with either frequency hopping or spreading. A wideband, fast tuning jammer or receiver is necessary to counter LPI waveforms in radar or comms applications.

This webinar discusses common frequency converter architectures and design tradeoffs, including multi-stage frequency conversion. We discuss unique features of upconversion systems versus downconverters. Example discussed include X-band (8-12 GHz) converters, 2-18 converters and Ka-band converters with up to 1 GHz of instantaneous bandwidth. We also discuss digital conversion systems, which when combined with wideband frequency converters give rise to system applications such as digital receiver/exciters (DREXs), communication modems and digital RF memories (DRFMs). Characterization of wideband frequency conversion systems will be discussed, with an emphasis on measurement of key parameters such as spurious-free dynamic range, P1dB, IP3, phase noise, harmonics and LO leakage. Finally, we discuss phase coherence of a multi-channel frequency conversion system, which is useful in phased array, MIMO and direction-finding (DF) applications.

PLAN NOW TO ATTEND: International & Foreign Military Sales (FMS) Electronic Warfare Symposium, May 15-19 in Atlanta

U.S. Foreign Military Sales (FMS) and Direct Commercial Sales (DCS) of sensitive military technologies, like Electronic Warfare, can be difficult to understand and navigate for International Partners and U.S. Defense Industry. U.S. Export laws, such as the International Traffic in Arms Regulations (ITAR), requirements for Export Licenses, and in some cases Congressional approval can be confusing and complicate the sale of EW systems and associated technical support. This conference provides an educational opportunity and forum for US Government, U.S. Defense Industry, Academia. and International partners to share information and provide updates on FMS and DCS program policy, processes, and improvements.

INDUSTRY NEWS: Army Seeks Electromagnetic Pulse Artillery
If the U.S. Army has its way, America’s next secret weapon may be an electromagnetic pulse artillery shell that paralyzes an enemy city. These special shells won’t carry high explosive. Instead they will emit EMP bursts, or some other non-kinetic technology, to disrupt the computers, radio communications, Internet links and other ties that bind modern societies. And do so without creating any physical damage. This is sort of a twenty-first-century version of the neutron bomb, that notorious Cold War weapon designed to kill Soviet soldiers through a burst of radiation, while inflicting little damage to property. Except this weapon targets the radio frequency networks that keep a nation functioning. (Scout Warrior)

INDUSTRY NEWS: Cyber/EW, Aviation, Air Defense, Artillery: CSA Milley’s Priorities
The Army needs new weapons to fight for the air, the airwaves and cyberspace against a high-end adversary such as Russia or China, Chief of Staff Gen. Mark Milley said today. While the Army’s near-term readiness to "fight tonight" remains Milley’s top priority, there’s enough progress on readiness – and enough potential for a budget boost under Trump – to spend more time and money on long-term modernization, which determines the Army’s readiness to fight tomorrow.

INDUSTRY NEWS: The Moscow School of Hard Knocks: Key Pillars of Russian Strategy
The scandal over Russian meddling in the U.S. presidential election is only the latest in a series of geopolitical contests with Russia in which Moscow has often gotten the better of the United States. The "new Cold War" isn’t going all that well for anyone besides Vladimir Putin. Washington certainly has the least to show for it. Following public outcry, the Obama administration released intelligence on the Russian hacking operation, but the clumsily written disclosures only made Vladimir Putin look bigger and badder. Meanwhile President Obama’s ambiguous threats to respond at a "time and place of our choosing" obscured what costs, if any, Russia paid for such chicanery. (War on the Rocks)

INDUSTRY NEWS: With a Shrinking Fleet IAF Has Tough Choices Ahead
The IAF has just 33 squadrons, nine short of the 42 squadrons needed to tackle China and Pakistan together, says Ajai Shukla. On December 28, Air Chief Marshal Arup Raha, the retiring Indian Air Force chief, declared in New Delhi that the IAF requires 200 to 250 medium fighters in addition to the 36 Rafale multi-role fighters that were contracted with French vendor Dassault earlier this year. The 36-Rafale contract was signed for €7.8 billion (Rs 55,600 cror/Rs 556 billione). Another 200 Rafales, or comparable fighters, would require €43.3 billion (Rs 310,000 crore/Rs 3.1 trillion), far beyond India’s means given the current defence spending. (The Northlines)

INDUSTRY NEWS: How Russia's Military Plans to Counter the Pentagon's Drone Swarms
Over the past decade, Russian armed forces and Russian defense industry have made strides in developing, testing and fielding domestically produced unmanned aerial vehicles(UAVs). While lagging behind their Western and East Asian counterparts in reach, distance and strike capability, Russia nonetheless was successful in using smaller and lighter UAV concepts for intelligence, surveillance and reconnaissance (ISR) purposes, both at home and in conflicts abroad. In fact, Russian Ministry of Defense (MOD) officially states that ISR remains the primary purpose for its various UAV platforms. More specifically, the war in Eastern Ukraine showcased Russia's use of unmanned aerial systems that enhanced Russian-allied forces' ability to more accurately target Ukrainian opposition and gain significant advantage on the battlefield.
