Measuring noise figure using Gain Method

For those into radio astronomy would know the significance of having ultra-low noise figures. Lower the noise figure, the more sensitive your receiver becomes. Noise figure is a unit of measure that tells us how much noise, for example, your amplifier is adding to the

EM simulation over a PCB designed by you

Doing electromagnetic simulations on your PCB layout can be a difficult task. The main reason being the tremendous effort required in porting your PCB layout data over to the 3D EM simulation software. Fortunately, new updates to the EM solver tools have made our work
