Portable Non-Linear Junction Detector
The Portable Non-Linear Junction Detector transmits at 2.4GHz-2.5GHz while receiving harmonics at 4.8GHz-5.0GHz and 7.2GHz-7.5GHz (second and third harmonics). Maximum transmit power reaches 0-4W EIRP in pulse mode. Receiver sensitivity operates at less than -125dBm, enabling detection from 4 meters or greater. The internal lithium battery provides over 4 hours of continuous operation. Device dimensions measure 370mm by 96mm by 38.5mm (±5mm) with a 100cm telescopic rod. Total weight is 0.5kg (±0.1kg), enabling portable deployment without fatigue.
The unit operates across -30°C to +55°C and tolerates up to 93% relative humidity without condensation. It complies with B-level product standards per GA1236-2015. The device penetrates 370mm thick brick walls, meeting C-level penetration standards. LCD display shows received harmonic signal strength in real-time. Audio alerts work through headphones or external speakers, while vibration feedback enables silent operation during sensitive sweeps.
The Portable Non-Linear Junction Detector deploys at corporate headquarters, government facilities, embassies, and correctional institutions to identify concealed electronic devices. Border security teams locate hidden communications equipment during passenger screening. Military operations sweep secure compounds for covert transmitters and eavesdropping apparatus. Airport security integrates the detector into baggage inspection procedures to identify prohibited electronic items.
Tactical Supply Pakistan provides the Portable NLJD with proven reliability across demanding operational environments. The brand delivers advanced detection technology with intuitive operation and responsive technical support.
How does the device distinguish between true semiconductors and corroded metal?
This NLJD analyzes second versus third harmonic ratios. True P-N junctions generate stronger second harmonic signals, while corrosion produces stronger third harmonic responses. Operators use the LCD display to differentiate them and eliminate false alerts.
