  • Use of smith chart to compensate for missing data on network performance at lower frequency
    Patent number: 8056034
    Abstract: A method is provided to use a Smith Chart technique to obtain frequency domain network performance information corresponding to a passive network including one or more passive devices comprising: receiving first data representing a first Smith Chart plot of coefficients representing measured mismatch between a source impedance of a network and a load impedance of the network for higher frequency components; and extrapolating a predicted substantially spiral shaped second Smith Chart plot of coefficients based upon the first data, which includes a coefficient representing predicted mismatch between the source impedance of the network and the load impedance of the network for lower frequency components.
