0.1 hz to 110 ghz noise diodes general specifications: output white gaussian noise operating 0?c to +55?c temperature for nc100 series -55?c to +125?c for all others storage temperature -65?c to +150?c specifications subject to change without notice. noise com's noise diodes are the fundamental building blocks of all noise systems. 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. applications: built-in test equipment (bite) ? dither circuitry for a/d converters 30 www.noisecom.com cathode c r + 15v rf c 3 1 2 r l (f c ) r l f c = low frequency cut-off typical bias circuit for nc100 series r = 150k for nc200 series r = 15k for nc300/400 series r = adjust for performance r l = load resistor for recommended value, see charts on page 31 nc100/200/300/400 series .com .com .com .com 4 .com u datasheet
