    摘要: Methods and apparatuses for transformer signal coupling for flip-chip circuit assemblies are presented. A device for coupling dies in flip-chip circuit assembly may include a first die associated with a first fabrication process and a first inductor physically coupled to the first die, where the first inductor receives an RF input signal. The device may further include a second die associated with a second fabrication process, and a second inductor physically coupled to the second die, where the second inductor is positioned so the first inductor can inductively couple the RF signal in the second inductor. A method for providing an inductive coupling between dies may include fabricating a first inductor on a first die using a passive process, fabricating a second inductor on a second die using a semiconductor process, and assembling each die so the first and second inductor are configured as a transformer.
