The NC346A is a broadband calibrated noise source for precision noise figure measurements, operating from 10 MHz to 18 GHz with an EXR of 5 to 7 dB. It features a VSWR of less than 1.15:1 up to 5 GHz and less than 1.25:1 from 5 to 18 GHz. Available with SMA male, precision APC3.5 male, N male, APC7, or N female connectors, it has a typical DC current draw of 15 mA at +28 VDC±2 VDC and includes a built-in regulator. The temperature coefficient is less than 0.009 dB/°C and the voltage coefficient is less than 0.002 dB/%∆V. Operating temperature ranges from 0°C to +55°C. The device includes NIST-traceable calibration data and has a physical dimension of 0.50 inches for SMA and APC3.5 versions, with a mounting bracket available as an option.
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.
