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.

Built-in test equipment (BITE)
Dither circuitry for A/D converters
