Nonlinear Junction Detector
The Nonlinear Junction Detector operates on a 2400MHz working band with transmission frequency spanning 2.4GHz to 2.5GHz. The device receives second and third harmonics at 4.8GHz–5.0GHz and 7.2GHz–7.5GHz respectively. Transmit power reaches 0–4W EIRP in maximum pulse mode, enabling detection range of 10 meters or greater. The unit measures 780mm × 177mm × 112mm and weighs under 1.8kg for field portability. Receiver sensitivity sits below -140dBm with a 30dB dynamic range, meeting GA1236-2015 C-level certification standards.
The device features a replaceable lithium battery delivering over 9 hours operational time during maximum pulse mode. Fast charging completes in 2.5 hours, minimizing operational downtime. The LCD display shows received harmonic signal strength directly. Audio alerts transmit through integrated headphones or external speakers for audible feedback. Vibration alerts provide silent notifications in noise-sensitive settings. Operating temperature ranges from -30°C to +55°C with humidity tolerance up to 95%RH at 40°C.
Security personnel deploy the Nonlinear Junction Detector during facility sweeps to locate concealed electronics. Operators scan walls, furniture, and structural elements to identify hidden cameras, listening devices, and unauthorized transmitters. Law enforcement units use it in detention facilities and secure areas. The device detects any semiconductor junction regardless of power status. Military and government agencies employ it for counter-surveillance and confidentiality protection. Corporate security teams scan boardrooms to prevent unauthorized monitoring.
Tactical Supply Pakistan provides this detector with proven reliability for professional security applications across demanding environments. The extended detection range, high sensitivity, and multi-alert feedback position this as an effective threat detection tool.
Can this NLJD identify the specific type of electronic device after detection?
The detector signals semiconductor junction presence but cannot determine device type through detection alone. Operators must conduct visual inspection following initial alert. Harmonic frequency response provides device classification clues, but definitive identification requires physical access to the target.
