Minimum Noise Figure (Fmin): This is the smallest Noise Figure that the device can reach at a given frequency and bias, if it is optimally matched at the source.Equivalent Noise Resistance (Rn): This is a number with the dimension Ohm that indicates how fast the Noise Figure increases when we mismatch the input (source).

R347B -
Keysight Technologies
The Keysight R347B noise source covers a 26.5 to 40 GHz frequency range. This waveguide noise source allows you to make accurate and convenient noise figure measurements on millimeter-wave devices. The R347B provides highly precise broadband noise at the input of the system or component under test. The noise figure meter then processes the ON/OFF ratio of noise power present in the system IF, and provides an accurate reading of noise figure and gain. The R347B noise source has remarkable ENR stability over time, which allows longer recalibration cycles and more accurate noise figure measurements.

CNS346 Series -
Spanawave Corporation
The Spanawave CNS346 Series is designed for precision noise figure measurement applications. The superior VSWR characteristics reduce multiple reflections of the test signals and significantly increase the measurement accuracy of most noise figure set-ups. The CNS346 Series noise sources have broadband coverage and extremely good temperature and voltage stability, for the finest noise figure meter-compatible laboratory standards. Outputs of 6, 15.5 and 22 dB ENR are available, allowing the units to accurately measure noise figures up to 20 ,30 and 36 dB respectively.

LNA Series -
Teseq AG
Low noise amplifier with 12.5 dB of gain covering the nominal frequency range 1 MHz to 3 GHz and can be used in the range from 200 kHz to 4 GHz. With its high gain and low noise figure, it will significantly increase the sensitivity of virtually all spectrum analyzers and other RF measuring instruments. All measuring instruments have a 'noise figure', which is a measure of how good the instrument is at measuring low level signals, the lower this figure, the better, although the lowest signal level will still be governed by the measurement bandwidth. A typical spectrum analyzer may have a noise figure of 20 dB or more, whereas a typical receiver may have a noise figure of 10 dB. The preamplifier has a noise figure of typically 4 dB, significantly enhancing the low level performance of such instruments, enabling signals that were previously masked by noise to be seen.

MT7553 Series -
Maury Microwave Corporation
Noise Parameters are the non-50Ω extensions of Noise Figure, and are an important modeling and model validation tool to understand how a device-undertest’s performance changes as a function of source impedance. Noise Parameter measurements are typically performedusing a Vector Network Analyzer (VNA) to measure the S-Parameters of the DUT, and a Noise Analyzer (either Noise Figure Analyzer NFA or Spectrum Analyzer SA) to measure the noise power of the DUT. Noise parameters are calculated from a combination of knownsource impedances, S-parameters and noise powers.
