Higher data rates and more complex modulation schemes are requiring digital engineers to take into account the analog and RF performance of the channels to a much greater degree than in the past.</div> <p><a href="http://defenseelectronicsmag.com/white-papers/guide-making-rf-measurements-signal-integrity-applications" target="_blank">read more</a></p> http://defenseelectronicsmag.com/white-papers/guide-making-rf-measurements-signal-integrity-applications#comments Military Defense Electronics White Papers Test & Measurement Tue, 21 Mar 2017 13:31:00 +0000 9841 at http://defenseelectronicsmag.com Mobile Device and Application Testing: Replacing the Live Network http://defenseelectronicsmag.com/test-measurement/mobile-device-and-application-testing-replacing-live-network <div class="field-deck"> Sponsored by Anritsu </div> <div class="node-body article-body">This paper describes the various methods of device testing available to mobile device application developers and how one of them, network simulation, offers valuable types of information not available from any other test method.</div> <p><a href="http://defenseelectronicsmag.com/test-measurement/mobile-device-and-application-testing-replacing-live-network" target="_blank">read more</a></p> http://defenseelectronicsmag.com/test-measurement/mobile-device-and-application-testing-replacing-live-network#comments Military Defense Electronics White Papers Test & Measurement Fri, 03 Feb 2017 21:06:00 +0000 9831 at http://defenseelectronicsmag.com Measurement of Radar Cross Section Using the VNA Master Handheld VNA http://defenseelectronicsmag.com/test-measurement/measurement-radar-cross-section-using-vna-master-handheld-vna <div class="field-deck"> Sponsored by Anritsu </div> <div class="node-body article-body">Radar cross section RCS is the measure of an object's ability to reflect radar signal in the direction of the radar receiver i.e. it is the measure of the ratio of backscatter per steradian (unit solid angle) in the direction of the radar (from the target) to the power density that is intercepted by the target. 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.
