C^OAXIALAMPLIFIED NOISE SOURCE

5 MHZ TO 500 MHZ

D^ESCRIPTION

available

from stock

The CNS7109 noise module is designed

for a wide range of applications. It fea-

tures high noise output amplitude for

uses ranging from encryption to jam-

ming. All biasing and amplification circuit-

ry is built-in making it easy to design into

your system. It features a built-in voltage

regulator for highly stable output even if

your DC supply lines are not.

A^PPLICATIONS

Common Noise Applications

1. Built-in IF Testing:

Highly stable flat over frequency noise

sources serve to provide built-in test

for an IF subsystem. By injecting a

stable signal reference through the IF

chain, one can calibrate the gain/loss

and frequency response. In addition,

the noise source can be used to set

up Eb/No for built-in stimulated BER

testing of digital demodulation.

CNS7109 TYPICAL DATA

1. Barrage Jamming:

The noise source is fed into the tuning

port of a VCO via a bias tee and a posi-

tive DC voltage. The random nature of

noise makes the output of the VCO to

hop around in a given frequency band

randomly making an ideal jamming sig-

nal. Further circuitry can be used

between the noise source and tuning

port to shape the noise probability den-

sity function (PDF) for the desired jam-

ming effect.

2. Random Number Generation for

Encryption:

S^{PECIFICATIONS}

• Frequency:

5 MHz to 500 MHz

Noise sources being truly random (not

pseudorandom) give the ultimate in

secure communication because of their

ability to generate a truly random num-

ber pattern. This can be used to seed

an encryption key for authentication.

The noise signal can be fed directly into

an A/D converter for sampling or a sim-

pler techniques might use a comparator.

Further shaping of the noise is often

employed whether either analog if in

front of the A/D converter or afterwards

using DSP.
