Definition
Non-Linear Junction Detectors (NLJDs) are specialized electronic devices designed to identify semiconductor components in electronic circuits or concealed devices by detecting non-linear junctions. These detectors emit a radio frequency (RF) signal, which interacts with non-linear junctions such as diodes, transistors, and other semiconductor elements present in electronic devices. When the RF signal encounters these junctions, it generates harmonic frequencies that are reflected back to the detector, allowing the device operator to locate hidden electronic components even when they are encased in metal or concealed within walls.
