This application note describes how a modern battery-powered / portable Microwave Vector Network Analyzer with Time Domain Gating can make it easy to do RCS tests on the flight line or in the field.</div> <p><a href="http://defenseelectronicsmag.com/test-measurement/measurement-radar-cross-section-using-vna-master-handheld-vna" target="_blank">read more</a></p> http://defenseelectronicsmag.com/test-measurement/measurement-radar-cross-section-using-vna-master-handheld-vna#comments Military Defense Electronics White Papers Test & Measurement Tue, 31 Jan 2017 17:17:00 +0000 9791 at http://defenseelectronicsmag.com Bandpass Filter Screens 0.7 to 6.0 GHz http://defenseelectronicsmag.com/components/bandpass-filter-screens-07-60-ghz <div class="node-body article-body">A digitally tunable filter provides adjustable passbands from 0.7 to 6.0 GHz. </div> <p><a href="http://defenseelectronicsmag.com/components/bandpass-filter-screens-07-60-ghz" target="_blank">read more</a></p> http://defenseelectronicsmag.com/components/bandpass-filter-screens-07-60-ghz#comments Communications Components Test & Measurement Fri, 21 Oct 2016 20:46:00 +0000 9781 at http://defenseelectronicsmag.com Frequency Synthesizer Tunes 3 to 6 GHz http://defenseelectronicsmag.com/components/frequency-synthesizer-tunes-3-6-ghz <div class="node-body article-body">A compact frequency synthesizer combines multiple source techniques for excellent spectral purity from 3 to 6 GHz.</div> <p><a href="http://defenseelectronicsmag.com/components/frequency-synthesizer-tunes-3-6-ghz" target="_blank">read more</a></p> http://defenseelectronicsmag.com/components/frequency-synthesizer-tunes-3-6-ghz#comments Communications Components Radar Fri, 21 Oct 2016 20:24:00 +0000 9771 at http://defenseelectronicsmag.com Frequency Dividers Tackle 0.5 to 18.0 GHz http://defenseelectronicsmag.com/components/frequency-dividers-tackle-05-180-ghz <div class="node-body article-body">A line of high-reliability frequency dividers has been developed for applications from 0.5 to 18.0 GHz in different division configurations. </div> <p><a href="http://defenseelectronicsmag.com/components/frequency-dividers-tackle-05-180-ghz" target="_blank">read more</a></p> http://defenseelectronicsmag.com/components/frequency-dividers-tackle-05-180-ghz#comments Communications Components Electronic Warfare Thu, 20 Oct 2016 20:58:00 +0000 9761 at http://defenseelectronicsmag.com Amplifier Boosts Forward and Backward http://defenseelectronicsmag.com/components/amplifier-boosts-forward-and-backward <div class="node-body article-body">A bidirectional solid-state amplifier provides 3 W output power from 30 to 3,000 MHz in a compact housing. </div> <p><a href="http://defenseelectronicsmag.com/components/amplifier-boosts-forward-and-backward" target="_blank">read more</a></p> http://defenseelectronicsmag.com/components/amplifier-boosts-forward-and-backward#comments Communications Components Electronic Warfare Thu, 20 Oct 2016 20:46:00 +0000 9751 at http://defenseelectronicsmag.com Coupler Passes DC, Power Levels to 200 W http://defenseelectronicsmag.com/components/coupler-passes-dc-power-levels-200-w <div class="node-body article-body">A bidirectional coupler can channel 200 W power from 225 to 450 MHz. </div> <p><a href="http://defenseelectronicsmag.com/components/coupler-passes-dc-power-levels-200-w" target="_blank">read more</a></p> http://defenseelectronicsmag.com/components/coupler-passes-dc-power-levels-200-w#comments Components Thu, 20 Oct 2016 20:39:00 +0000 9741 at http://defenseelectronicsmag.com Rockwell Collins Demonstrates Wideband HF from Airborne C-17 http://defenseelectronicsmag.com/systems-subsystems/rockwell-collins-demonstrates-wideband-hf-airborne-c-17 <div class="node-body article-body">A complex air-to-ground data link was performed from an airborne C-17 aircraft to a ground station using wideband high-frequency (WBHF) technology.</div> <p><a href="http://defenseelectronicsmag.com/systems-subsystems/rockwell-collins-demonstrates-wideband-hf-airborne-c-17" target="_blank">read more</a></p> http://defenseelectronicsmag.com/systems-subsystems/rockwell-collins-demonstrates-wideband-hf-airborne-c-17#comments Communications Systems & Subsystems Wed, 19 Oct 2016 16:28:00 +0000 9731 at http://defenseelectronicsmag.com <p>An airborne C-17 aircraft was part of a test examining the capabilities of performing air-to-ground communications using wideband high-frequency (WBHF) communications equipment.
