Novel Method for Noise Figure Measurement of Antenna Low Noise Amplifiers Optimized for a Trade-Off Between Gain and Noise Properties

Popis výsledku v původním jazyce

The best properties of antenna low noise preamplifiers can be achieved by the multi-objective optimization which generates a trade-off between the transducer power gain and noise figure in the form of Pareto front. However, as the resultant circuit designed in this way is not fully matched at the output, measuring the amplifier - unmatched neither to gain nor to noise figure - is quite difficult, especially in the case of very low noise figures. In this paper, a more accurate two-stage measurement method is presented, where both calibration and measurement stages contain improvements to end the device with standard impedances and increase needed overall measurement sensitivity.
