PRECISION CALIBRATED, OUTPUT ISOLATOR WR-22 WAVEGUIDE NOISE SOURCE MODULE, OUTP

PrecisionCalibrated, Output Isolator WR 22 Waveguide Noise Source Module, Output ENR of 15 dB, +28 VDC, 33 GHz to 50 GHz

The FMWNS2001 is a Q Band waveguide Noise Source module with output Isolator that operates over the full frequency range of 33 GHz to 50 GHz. The benefit of the output Isolator results in improved output port matching for more accurate measurements as well as protection of the noise diode from incident RF power. The microstrip assembly incorporates a millimeter wave noise diode screened for superior noise characteristics that results in highly stable and reliable performance. This module can be used in built-in test and laboratory applications, and can replace outdated gas tube noise sources. Addtional applications include noise figure measurements, millimeter wave radiometers, automotive radar, and reserach and development in mm-wave broadband wireless communication systems. The design operates at +28 Vdc with an output ENR level of 15 dB min and a noise output variation of < 0.01 dB/°C, < 0.1 dB/%V. Maximum Flatness across the frequency band is +/- 1.5 dB and output VSWR is 1.3:1 max with the isolator. Operating temperature range is 0°C to +85°C. The rugged package supports a WR-22 waveguide interface and a BNC connector for the DC voltage supply.
