Similarly, solving for R (I used … WebBoth open and short-circuited stubs are employed in this type of stub matching. However, the shorted stubs offer isolation in RF circuits, in which power supplies are present. For example, in RF amplifier circuits, the ends of the shorted-stubs are used to feed the bias voltages, and bypass the RF currents to the ground plane via a capacitor.
