Non-Linear Junction Detector (NLJD) – Detection of Hidden Electronic Devices in Any Environment

Phantom Technologies’ Non-Linear Junction Detector (NLJD) is a tactical counter-surveillance tool engineered to detect and locate hidden electronic components, even when they are powered off or in standby mode. By identifying the non-linear junctions present in semiconductors, NLJDs reveal covert devices embedded in walls, furniture, ceilings, equipment, or containers—making them indispensable for TSCM operations, military sweeps, diplomatic protection, and industrial espionage prevention.

Key Capabilities

Non-Linearity Detection
NLJDs detect the non-linear characteristics of semiconductor junctions, enabling the location of hidden electronic circuits, regardless of their power status.
Detects Powered-Off Devices
Capable of identifying devices that are switched off, dormant, or in passive mode, unlike RF scanners which require active transmission.
Penetrates Obstructions
Effectively locates electronics concealed behind walls, ceilings, under floors, inside furniture, or embedded in vehicles and equipment.
Multi-Frequency Operation
Uses dual or multiple transmission frequencies to optimize detection and minimize false positives in metallic or high-interference environments.
Cyber-Physical Surveillance Protection
Can assist in locating hardware implants or unauthorized electronic modules in cybersecurity-sensitive environments.
