Abstract

A magnetic circulator is incorporated into a multi-chip module using a microwave high density interconnect (HDI) structure. A prepackaged circulator can be inserted into a ready-made high density interconnected multi-chip module; this prepackaged circulator may use a stripline design having a signal line with two ground planes above and below the signal line, or a microstrip transmission line design having one signal line and one ground plane below the signal line. Alternatively a circulator can be manufactured directly in a high density interconnected multi-chip module, with a stripline, or a microstrip transmission line design.
