Of a fairly weak crop dominated by shorts, clickbait thumbnails, and affiliate-link product reviews, this Sierra Circuits Trace Talks episode is the only entry that promises actual engineering depth. Sierra Circuits is a PCB fab whose YouTube channel doubles as a technical education resource, and their interview format tends to pull useful working knowledge out of practicing engineers rather than rehashing tutorial-grade material.

The guest, Neil Jarvis, is positioned as an RF specialist, and the episode title — "RF must-knows for engineers" — suggests the kind of practical guidance that's hard to find outside of expensive trade conferences or paywalled application notes. Topics in this genre typically cover impedance control, stackup choices for high-frequency signals, why ground returns matter more than schematic-level designers expect, connector and via discontinuities, and the gap between simulation and measurement.

RF design is one of those domains where intuition built on lower-speed digital work actively misleads you, so hearing an experienced practitioner talk through the failure modes is genuinely valuable. The video has no description text, which is unfortunate, but the channel's track record and the named guest make it the safest bet here.

Caveat: if the episode turns out to be more interview-flavored than technical, the rest of the Trace Talks back catalog is still worth a browse.
