The NC346D is a calibrated noise source for precision noise figure measurements, offering an ENR of 19-25 dB and operating from 0.01 to 18.0 GHz. It features a maximum VSWR of 1.50:1 up to 18 GHz and 1.75:1 from 18 to 26.5 GHz, with a built-in regulator and +28 VDC ±2 VDC input at 15 mA typical. The connector is SMA male, and its physical dimensions are specified as 0.50 inches in length. Temperature coefficient is less than 0.009 dB/°C, and voltage coefficient is less than 0.002 dB/%∆V. Operation is rated from 0°C to +55°C. Calibration data is traceable to NIST and includes return loss measured in both on and off states up to 40 GHz.
The NC346 Series is designed for precision noise figure measurement applications. Each module’s low VSWR reduces multiple reflections and significantly increases the measurement accuracy for most noise figure test configurations.
