| SMN7106 SURFACE MOUNT AMPLIFIED NOISE SOURCE 200 KHZ TO 12 MHZ D ESCRIPTION The SMN7106 noise module is designed for a wide range of applications. It features high noise output amplitude for uses ranging from encryption to jamming. All biasing and amplification circuitry 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. 7106 7106 SMN7106 TYPICAL DATA S UITABLE FOR H IGH V OLUME P RODUCTS : The SMN7106 noise sources being surface mount, having a small footprint and available on tape and reel, make them ideal for production manufacturing. Traditionally packaged noise sources have been large and costly rendering them less suitable for all but the more expensive, exotic systems. Noise can now be thought of as lower cost, more reliable, smaller and easier to implement alternative to costly microprocessor based solutions such as PN generators, arbitrary waveform generators and DSP processors. S PECIFICATIONS * Frequency: 200 kHz to 10 MHz * Noise Power Spectral Density (No): -79 dBm/Hz APPLICATION NOTE Common Noise Applications 1. Barrage Jamming: The noise source is fed into the tuning port of a VCO via a bias tee and a positive 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 signal. Further circuitry can be used between the noise source and tuning port to shape the noise probability density function (PDF) for the desired jamming effect. 2. Random Number Generation for Encryption: Noise sources being truly random (not pseudorandom) give the ultimate in secure communication because of their ability to generate a truly random number 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 simpler 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.
