ESCRIPTION

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.

REQUIREMENTS

Micronetics fullband noise sources are

based on a coaxial design as the base

part. As standard options, noise

sources can be ordered with either

• Coaxial Isolator

• Waveguide Output

• Waveguide Isolator

TIONS

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.
