amp read (rfckt.amplifier, default.s2p ) Plot the noise figure of the amplifier 1. The simplest termination is either a short circuit or an open circuit. Draw Circles on Smith Chart Created using smithplot Function Copy Command Create an amplifier object from default.s2p. The impedance to be synthesized is reactive so the termination must also be lossless. It does not store any personal data.= \jmath 140\:\Omega\).

A Smith Chart is a specialized chart for visualizing complex numbers: numbers with both a real and imaginary part. Then all reflection coefficients inside the Smith chart would result in stability.

Above the critical frequency the stability circles are found outside the gamma 1 boundary of the Smith Chart. – It is based on a June 2011 IEEE MWCL Journal paper “A 3D Smith chart based on the Riemann sphere for Active and Passive Microwave circuits” thus the tool deals only with circles on the surface of the unit sphere. In that sense input and output stability circles were plotted on the smith chart and the conclusion was that the transistor is potentially unstable as shown in Fig. The circles that overlap the gamma 1 boundary of the Smith Chart that are below the critical frequency (the Stability Circle at the critical frequency is coloured red) imply potential instability. The 3D Smith chart Java tool is a new design instrument for all the active and passive microwave circuits:
