Precision Waveguide Calibrated Noise Source

The NW-W noise sources cover all major millimeter waveguide bands with high output, excellent flatness and ripple-free response.

The NW-W noise sources cover all major millimeter waveguide bands with high output, excellent flatness and ripple-free response. Utilizing millimeter wave noise diodes screened for superior noise characteristics and a microstrip antenna approach, the NW-W is a more stable noise source and a significantly more reliable unit than dated approaches currently on the market. Designed for both built-in test and laboratory application, these units can also replace outdated gas tube noise sources. Models are available up to 110 GHz (W-band). Applications include Noise figure measurement, millimeter wave radiometers, automotive radar as well as research and development in modern high frequency broadband wireless communication systems.
