What's New

Two Bronx radio operators face steep FCC fines after field agents track down illegal broadcasts using social media posts and audio-matching techniques. Learn how the Commission built its case and what unauthorized broadcasters risk going forward.

Modelithics and Spectrum Control team up to deliver measurement-validated models for a full line of high-reliability RF resistive components — with free 90-day trial licenses on the table for designers ready to put them to the test.

When cables become the culprit in radiated emissions failures, an RF current probe can catch what near-field probes miss. This installment of EMC Bench Notes walks through measurement technique, transfer impedance math, and a downloadable E-field calculator for pass/fail estimation.

Supercapacitors are showing up everywhere from EVs to renewable energy systems — but one safety standard determines whether they're fit to ship. This guide breaks down what UL 810A actually requires, where manufacturers get tripped up, and one costly rating mismatch to watch for.

The FCC wraps up a major spectrum auction with billions in winning bids, opening new mid-band wireless capacity and setting the stage for an even bigger auction ahead. See what the results mean for spectrum availability and the industry's next regulatory milestone.

The FCC clears toy drones for U.S. sale following a national security review, but only those meeting strict new criteria qualify. Find out what weight and range limits determine which drones make the cut, and which stay banned.

No new harmonized EN EMC standard has cleared the OJEU since 2022 — and the backlog is only getting more tangled. Between a landmark court ruling, a copyright fight with ISO/IEC, and the EU's pivot toward Common Specifications, the rules for proving compliance are shifting under manufacturers' feet.

A power cord might look like a commodity part, but it's one of the most heavily regulated subsystems in any globally distributed device. Five-country certification rules — covering plugs, cables, connectors, and cord sets — can quietly stall shipments if engineering teams get the documentation wrong.

A common ESD flooring assumption gets the physics backwards — and it could be steering facilities toward the wrong resistance category entirely. Drawing on decades-old Bell Labs research, this piece traces exactly where a CDM event actually begins, and why flooring resistance alone won't protect against it.

A glowing ad claim or an overstated label can do more legal damage than a flawed component ever could. From decades-old case law to the recent Johnson & Johnson talc verdict, this piece breaks down how marketing language becomes courtroom evidence — and how manufacturers can stay out of the crosshairs.
