Fullband High ENR Microwave Noise Sources S, C and X Bands
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 spe­cially 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 pack­aged diodes and beryllium copper bel­low assemblies which are not only are less reliable, but use hazardous materi­als.

Common Applications
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.
