SMN7105 1/2 INCH SURFACE MOUNT AMPLIFIED NOISE SOURCE 100 KHZ TO 3 MHZ D ESCRIPTION The SMN7105 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. SMN7105 TYPICAL DATA S UITABLE FOR H IGH V OLUME P RODUCTS : The SMN7105 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 an easier to implement alternative to costly microprocessor based solutions such as PN generators, arbitrary waveform generators and DSP processors. S PECIFICATIONS • Frequency: 100 kHz to 3 MHz • Noise Power Spectral Density (No): -73 dBm/Hz (min) 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.

1. 物料型号: - 型号:SMN7105 - 描述:1/2英寸表面贴装放大噪声源

2. 器件简介: - SMN7105噪声模块设计用于广泛的应用,具有高噪声输出幅度,适用于从加密到干扰等多种用途。所有偏置和放大电路都内置,便于系统设计。它具有内置电压调节器,即使直流供电线路不稳定,也能保持高度稳定的输出。

3. 引脚分配: - PDF中提供了两个引脚图,一个显示了大型焊盘和小焊盘,另一个显示了“+12和噪声”以及“GND”的焊盘布局。“+”号位于组件边缘,焊盘超出边缘0.02英寸。

4. 参数特性: - 频率:100 kHz至3 MHz - 噪声功率谱密度(No):至少-73 dBm/Hz - 噪声功率(N):-8 dBm - 频谱平坦度:1 dB(总窗口) - 偏置:12 Vdc内部调节 - 最大电流消耗:35 mA - 峰值因子:5:1 - 工作温度:-55至+85°C - 存储温度:-55至+125°C

5. 功能详解: - 该模块适用于干扰和加密等应用。随机噪声使得VCO的输出在给定频带内随机跳跃,形成理想的干扰信号。噪声源可以用于生成真正的随机数模式,用于加密通信。

6. 应用信息: - 干扰:将噪声源输入VCO的调谐端口,通过偏置Tee和正DC电压,输出的随机性使得VCO的输出在给定频带内随机跳跃,形成理想的干扰信号。 - 加密:噪声源是真正随机的(非伪随机),为安全通信提供了最终的保障,因为它们能够生成真正的随机数模式,这可以用于种子加密密钥进行认证。

7. 封装信息: - SMN7105为表面贴装式,体积小,可提供胶带和卷轴,适合生产制造。传统封装的噪声源体积大且成本高,不太适合除了更昂贵、更特殊的系统之外的所有系统。现在可以将噪声视为成本更低、更可靠、体积更小、更易于实施的替代方案,如PN发生器、任意波形发生器和DSP处理器等基于微处理器的解决方案。
