Data Sheet NC 100/200/300/400 Series
0.1 Hz to 110 GHz Noise Diodes
Noisecom’s noise diodes are the fundamental building blocks of The NC100 and NC200 Series diodes are designed for audio all noise systems. They are hand-picked for performance char-and RF applications. The NC300 and NC400 Series diodes are acteristics that make them ideally suited to broadband noise designed for microwave applications in which a 50-ohm imped-generation with flat response. ance is required. All Noisecom noise diodes deliver symmetrical white Gaussian Typical small signal impedance of the NC300 and NC400 Series noise and flat output power versus frequency. The diodes are is 10-20 ohms after a diode is biased. The output level is higher hermetically sealed and available in a wide variety of package at low frequencies with low currents and driving the diodes with styles. Special package configurations or screening processes higher current results in greater output at higher frequencies. are available upon request. Audio & VHF Types
