Maxwell’s classic Treatise returns after 115 years
New Bedford, Mass. — In June 2023, a rare 1881 copy of James Clerk Maxwell’s An Elementary Treatise on Electricity turned up in a West Virginia library. In remarkably good condition, the book was returned to its original library in New Bedford. The book was last checked out in what looks like 1908, making it…

FAQ: Antenna-in-package answers the “last mile” RF challenge, Part 2
If you think antennas must live “outside” a circuit, think again: they can also be housed in a small package adjacent to the active components they serve. The previous part established the context and rationale for AiP; this part continues the exploration. Who are some of the AiP technology suppliers or OEMs? ASE, a leading…
FAQ: Antenna-in-package answers the “last mile” RF challenge, Part 1
If you think antennas must live “outside” a circuit, think again: they can also be housed in a small package adjacent to the active components they serve. The RF signal chain has become increasingly integrated in the past years. Whether by merging RF circuitry with the digital function onto a single die or by co-locating…
IMS 2023 roundup: semiconductors and microwave components
Through photos and videos, EE World covers some of the active and passive components that RF and wireless engineers need to connect us all. The exhibit hall at the 2023 International Microwave Symposium in San Diego consisted of 560 exhibitors, too many for this editor to visit in three days. For 2023, we improved our…
IMS 2023: keynote analyzes early undersea cables
In EE World videos from the 2023 International Microwave Symposium, engineers received a history lesson on early transatlantic cables through an analysis using today’s methods. Plus, a demonstration of a 1944 radio using a razor blade as a rectifier. Modern equipment provided an automated Morse code signal.
How RF measurements verify satellite links
Noise measurement, LO substitution, receiver stress testing, power measurement, CCDF and PAPR characterization, and antenna-pattern measurement play critical roles in link budget, bit-error rate, and SNR requirements. Low-Earth orbit (LEO) satellite systems are being deployed for mission-critical use cases at an accelerating rate. This brings associated critical test requirements that, if not performed accurately, could…
