They are hand-picked for performance characteristics that make them ideally suited to broadband noise generation with flat response. All Noise Com noise diodes deliver symmetrical white Gaussian noise and flat output power versus frequency. The diodes are burned-in for 168 hours, meet MIL-STD202, and are hermetically sealed. Noise Com noise diodes are available in a wide variety of package styles, and in special configurations on request. The NC100 and NC200 Series diodes are designed for audio and RF applications. The NC300 and NC400 Series diodes are designed for microwave applications in which a 50-ohm impedance is required. Typical small signal impedance of the NC300 and NC400 Series is 10-20 ohms when a diode is turned on. Typically the output level is higher at low frequencies with low currents. Driving the diodes with more current results in more output at higher frequencies. General Specifications: Output Operating temperature White Gaussian Noise 0C to +55C for NC100 series -55C to +125C for all others Storage temperature -65C to +150C Specifications subject to change without notice.
