Non Linear Junction Detection
The HAWK Non-Linear Junction Detector (NLJD) was
introduced in the mid 1980's for the detection
of hidden electronic circuits, and has undergone
many development changes since it first appeared
on the market. The HAWK Model 450 is Winkelmann's
latest non-linear junction detector.
A non-linear junction (NLJ) is a junction, which
conducts electricity in one direction only. Such
junctions occur in every diode, transistor and
integrated circuit (IC).
The HAWK NLJD Model 450 locates concealed electronic
circuits incorporating transistors and diodes
(NLJs), whether active or inactive. The unit therefore,
is an essential tool for electronic countermeasure
searches, explosive ordnance disposal and a variety
of security evaluation procedures.
HAWK
450 System Introduction
The Hawk Model 450 incorporates the very latest
technology in non-linear junction evaluation.
Radio Transmitters, Power Amplified Microphones,
Electronic Timers all contain NLJs and will be
detected by the HAWK even if they are embedded
in walls and switched off.
A pure radio frequency signal is transmitted by
HAWK and absorbed by a non-linear junction, which
inturn re-radiates on harmonically related frequencies,
which are picked up by HAWK's sensitive receivers.
The transmitter and two receivers are frequency-synthesised
thereby completely eliminating frequency drift.
The transmitter design uses a crystal-reference
synthesiser at output frequency for spectral purity,
efficiency and linearity. The two receivers have
extemely good RF isolation and are locked to the
transmitter frequency.

450 System Description
Every element of the HAWK 450 has been designed
to create an instrument that satisfies the very
highest standards, in terms of functionality,
ease of operation and reliability. As a result
the Winkelmann HAWK 450 offers a performance that
is second to none in terms of quality, cost and
operation.
The HAWK combines an extermely pure radio transmission
with very selective and sensitive receivers. Using
our unique technology the unit will automatically
compare the second and third harmonic return signals
and indicates whether the response is from an
electronic or natural source.
This advanced system consists of the main unit
fitted into a carrying pouch with shoulder strap,
antenna, rechargable snap-on batteries, battery
charger, headphones, test target and operator's
manual all housed in a compartmentalised flight
case.
The HAWK 450 is an integral self-monitoring system
with crystal control phase lock loop stability.
No fine-tuning is required.
Will detect and locate hidden electronic devices
(bugs & taps) whether powered or not.
2nd & 3rd harmonic detection and demodulation.
Variable output power from 60mW to 1Watt.
Omni (non-polarised) antenna.
Small, lightweight and compact only 1.5kg.
Uses snap-on rechargable batteries or mains. |
