How One Military Plane Fights California Wildfires
The California Air National Guard used the MQ-9 Reaper unmanned aerial vehicle (UAV) to help fight the Carr and Mendocino wildfires by capturing bird’s eye images and videos of the damage.
Marines' “Mega Drone” Illustrates Need For High-Efficiency Microwave Power Modules
A recent Military article revealed details about the US Marines' “mega-drone,” an impressive Group 5 aircraft (the largest class of military UAV) that can carry the same payload as an F-35B and fly a radius of up to 700 nautical miles at 30,000 feet, and will be able to fill “an extremely broad range of missions.
Harmonic Injection Doubles Ultra-Wideband TWT RF Output
Using harmonic injection on an ultra-wideband TWT is a relatively new concept that works to cancel the naturally-generated second (and/or third) harmonic within the TWT, and therefore recover the available beam power back into the low-end fundamental frequencies.
What’s Better – TWTAs Or SSPAs?
Depending on the specific application and end-customer requirements, different parameters may be critical to the amplifier design. The ultimate goal is to create an amplifier that is specification compliant, reliable, low-cost, and easy to maintain.
How To Meet AS9100 Requirements As A Defense Subcontractor
Since the construction and maintenance of aircraft involves a variety of products, quality and compliance become major concerns. For these reasons, manufacturers supplying the aerospace industry face the decision whether or not to become AS9100 certified.
How To Improve Spurious Levels In Pulsed RF Amplifiers
This white paper is meant to assist designers in figuring out how to lower these spurious levels in order to improve system accuracy and reduce any potential negative effects.
White Paper: Changing EW Environment Requires Even Higher RF Power
By Joe Hajduk, CEO, dB Control
The theme of AOC's 47th Annual International Symposium and Convention is "Electronic Warfare in a Changing Environment." One aspect of the EW environment that's changing rapidly is the increased sophistication and persistence of threat radars. Today's threat radar detection systems must rapidly discriminate between real targets and those created by digital RF memories.
Changing EW Environment Requires Even Higher RF Power
The theme of AOC’s 47th Annual International Symposium and Convention is "Electronic Warfare in a Changing Environment." One aspect of the EW environment that’s changing rapidly is the increased sophistication and persistence of threat radars. Today’s threat radar detection systems must rapidly discriminate between real targets and those created by digital RF memories (DRFMs). A DRFM captures signals, digitizes them, reconverts them to their analog origin, and then rebroadcasts them, usually after modifying the signal based on a library of known emitters. The rebroadcast signal can be altered to change the target’s radar cross-section, range, speed, angle of arrival, and direction. It can also create false targets behind the target (reactive jamming) and ahead of it (predictive jamming) to trick radar detection systems into mislocating or misidentifying the target.
