Abstract:
The consideration of electromagnetic interaction between spurious modes in metal packages and its enclosed microwave circuit (MMIC) in a circuit simulator is an important topic in circuit design. In this paper a novel method is described to determine mutual coupling networks for incorporation of this parasitic coupling into a SPICE based circuit simulator. For simple package shapes the coupling networks can be determined analytically, whereas full-wave simulations are needed for more complex ones. To shorten the duration, time-domain simulators need for analyzing a high-Q structure, Prony’s method is applied to extract circuit parameters from short time sequences.<br>
