DESCRIPTION
Micronetics line of fullband noise
sources are specially designed for built-
in test and calibration where there is
significant path loss between the noise
source and the device.
This family of high output fullband noise
sources with their compact size are spe-
cially designed for ease of integration
into microwave systems.
With their rugged and stable design, the
heart of these noise sources is a small
chip and wire hermetic noise module.
This is embedded in the housing with a
precision launch to the coaxial jack.
This design gives is much more stable
and rugged than traditional coaxial
noise sources which rely on pill pack-
aged diodes and beryllium copper bel-
low assemblies which are not only are
less reliable, but use hazardous materi-
als.

Radar Built-in Test/Calibration; where there is significant path loss between the noise
source and the receiver. For example, a 30dB coupler can be used to feed the test
noise signal into the receiver which minimized noise figure while still allowing 25 dB
ENR.

Jamming Systems; these high output devices, when used in conjunction with power
amplifiers, offer an efficient means to jam RF/microwave signals.
Antennal Calibration; high output noise can be used for antenna calibration to counter
the effects of over-the-air transmission loss.
