By Timothy Hegarty, Applications Engineer, Texas Instruments This article compares electromagnetic compatibility (EMC) requirements in automotive, industrial and defense product family standards, specifically various test parameters, test equipment, test setups and test methods for radiated emissions (REs). Much like the treatment of conducted emissions [1] in part 1 of this two-part article series, the […]

DC-DC buck controller integrates active EMI filter
Texas Instruments introduced a new family of synchronous DC/DC buck controllers that enable engineers to shrink the size of the power-supply solution and lower its electromagnetic interference (EMI). Featuring an integrated active EMI filter (AEF) and dual-random spread-spectrum (DRSS) technology, the LM25149-Q1 and LM25149 enable engineers to cut the area of the external EMI filter […]
Safety-critical-certified graphics processors target high-integrity cockpit display, navigation, synthetic vision apps
Abaco Systems, Inc. and CoreAVI announced an extension of their partnership through the signing of a licensing agreement that allows Abaco to implement the AMD Embedded Radeon E9171 GPU, associated COTS-D hardware IP, and Vulkan graphics and compute capabilities from CoreAVI into a new rugged embedded graphics processor to be produced and delivered by Abaco. […]
SBC, avionics I/O boards optimized for flight-certifiable applications
The SBC314C single-board computer and RAR15XC avionics data bus communications XMC mezzanine board are for embedded flight-certifiable applications. Previously only available as part of the FORCE2C rugged line replaceable unit (LRU), the two are now each available as separate boards. The SBC314C 3U VPX single board computer, based on the NXP QorIQ T2081 Multicore Communications […]
Wild blue yonder for next generation of electronics 3D printer
BotFactory says it has been awarded by the U.S. Air Force AFWERX program a Phase II Small Business Innovation Research (SBIR) grant worth $750,000. Over the next 15 months BotFactory will work closely with its partners at the 402th EMXG/MXDEK/REARM Lab in Robins AFB to develop a fully-automated desktop machine for on-site, on-demand 3D Printing […]
When audacious engineering leads to major success, Part 4: Apollo Lunar module
The Mars Rover Sky Crane, SpaceX Self-Landing Booster, and the Apollo Lunar Lander are just a few examples of dramatic, radically unconventional thinking, leading to astounding successes. While we now consider a lunar in-orbit rendezvous as routine, the viability, and risk of even a more-basic Earth-orbit link-up was a major concern at the time […]
When audacious engineering leads to major success, Part 3: Apollo Mission profile
The Mars Rover Sky Crane, SpaceX Self-Landing Booster, and the Apollo Lunar Lander are just a few examples of dramatic, radically unconventional thinking which led to astounding successes. Time and distance have a way of blurring the hard edges, sharp points, and intense disputes which accompany innovation. Years later, what once seemed ridiculous or foolish […]
Filters offer ‘brick-wall’ performance to 7 GHz for semiconductor and IC testing
Two new filter series for high frequency testing applications–-LC17 and HC17-–provide brick wall characteristics and performance to 7 GHz making them candidates for audio-digital-conversion and digital-audio-conversion (ADC/DAC) test set ups. Such signal conditioning testing is especially important for semiconductor chips and integrated circuits where testing frequencies continue to trend higher and higher. Relevant markets include […]
When audacious engineering leads to major success, Part 2: Mars Rovers
The Mars Rover Sky Crane, SpaceX Self-Landing Booster, and the Apollo Lunar Lander are just a few examples of dramatic, radically unconventional thinking, leading to astounding successes. You have undoubtedly been awed by the stunning and fully successful landing of the Mars Perseverance Rover on February 18, 2021. It used a radical, hovering “Sky […]
When audacious engineering leads to major success, Part 1: SpaceX booster
The Mars Rover Sky Crane, SpaceX Self-Landing Booster, and the Apollo Lunar Lander are just a few examples of dramatic, radically unconventional thinking, leading to astounding successes. Bringing a major engineering project from concept to successful conclusion is a combination of often-elusive factors of skill, understanding, determination, risk, diligence, perseverance, good fortune (luck), and many […]
