Noise Generator Component for Entropy Source Modules

Product Specifications

Technical details and manufacturing context for Noise Generator

Definition

The Noise Generator is a specialized electronic component within the Entropy Source Module, designed to produce random electrical noise signals. It serves as a fundamental source of randomness for cryptographic applications, security systems, and random number generation. The component leverages electronic noise phenomena such as thermal noise (Johnson-Nyquist noise), shot noise, or avalanche breakdown in semiconductor junctions to generate truly random electrical signals. These signals are then amplified and conditioned for use in entropy collection systems. The device is characterized by an output frequency range of 0.1–100 MHz, covering audio to RF noise generation, with an adjustable output amplitude from -60 to 0 dBm. Amplitude flatness is maintained within ±1.5 dB over the full frequency range, and the output impedance is matched to 50 Ω systems. The noise spectral density ranges from -160 to -140 dBm/Hz, indicating white noise characteristics. The operating temperature range is -20 to 70 °C, with a storage temperature range of -40 to 85 °C. The supply voltage is 9–36 V DC with reverse polarity protection, and the supply current is 50–150 mA at nominal voltage. The connector type is SMA (female, 50 Ω). Dimensions are 80×60×25 mm without connectors, and weight ranges from 200 to 300 g depending on options. The IP rating is IP40 (indoor use only) per IEC 60529. Materials include semiconductor substrate, metal contacts, and encapsulation material. All listed parameters are reference ranges for directory purposes; model-specific values and standards must be verified with the legal manufacturer or supplier.

Working Principle

The Noise Generator operates by exploiting fundamental electronic noise sources. Thermal noise arises from the random motion of charge carriers in a conductor, producing a voltage fluctuation proportional to temperature and bandwidth. Shot noise occurs due to the discrete nature of charge carriers crossing a potential barrier, such as in a semiconductor junction. Avalanche breakdown in a reverse-biased junction generates a cascade of carriers, producing significant noise. These noise signals are inherently random and are amplified using low-noise amplifiers, then conditioned (e.g., filtered, leveled) to provide a stable output. The output is delivered via a 50 Ω SMA connector, ensuring compatibility with standard RF systems. The device is powered by a 9–36 V DC supply, with internal regulation and protection. The generated noise is used as an entropy source for cryptographic and security applications.
