how biasing design for fhx35x transistor for obtained minimum noise figure
 

Re: FET transistor

Hi!

For obtaining minimum noise figure U should first obtain the noise parameters of the transistor though experiment, simulation, or datasheets. Then, using these parameters u can draw constant noise figure circles on the smith chart. considering other options like gain, stability, and bandwidth the optimum point is found.
