We are pleased to share a new technical blog by Keith Armstrong titled:
“Audio noise break-through from the UHF band (i.e. 300MHz - 3GHz)”

As wireless communication systems continue to expand rapidly, many engineers now face new EMC challenges — particularly from UHF band interference — that were never addressed in traditional textbooks or courses.

In this latest blog, Keith explores how modern mechanical and PCB designs can unintentionally act as antennas, leading to unintended demodulation and intermodulation in opamps and other semiconductor devices. The result: unpredictable low-frequency noise, even in audio circuits.
