Description
Overview
The QuinStar QNS-FB12LW is a millimeter-wave noise source designed for measuring noise figure of amplifiers and receivers across the 50–110 GHz frequency range. It features stable noise power output, high switching speed, and relatively flat high output power, eliminating the need for traditional gas tube noise sources in RF and microwave testing applications.
Key Features
- Frequency coverage: 50–110 GHz in standard waveguide bands
- W-band fullband coverage with very flat Excess Noise Ratio (ENR)
- Stable noise power output across frequency range
- High switching speed for rapid noise figure measurements
- Relatively flat output power characteristics
- Integral isolator for improved VSWR performance
- Careful device selection and special cavity design
- Stable performance across temperature and time variations
Applications
- Noise figure measurement for amplifiers and receivers
- Calibration and built-in test functions in sensitive receiver subsystems
- Radiometer and measurement instrument testing
- Replacement for traditional gas tube noise sources
- Subsystem and special test equipment applications
