Removing package effects from microstrip moment method calculations

Abstract

The electromagnetic behavior of microstrip circuits often depends on the package that surrounds the circuit. This is especially true if the package is electrically large. The importance of a damped enclosure for modeling and operating MMIC (monolithic microwave IC) circuits is discussed, a method of damping enclosures is presented, and an efficient technique for applying the method of moments so as to determine the significance of the package effects on full-wave simulations is outlined.<>
