DESCRIPTION
Noise diodes are the smallest,
most inexpensive and versatile
noise products available from
Micronetics. They are gener-
ally used as the foundation for
building larger noise sources
and test instruments, or in
systems where a basic noise
source is required, but space is
limited. These diodes all have
extremely wide bandwidths,
making them ideal for use in a
broad, and nearly limitless,
range of applications. They
are available in chip form as
well as surface mount and
axial lead packaging.
