GaN GS66508B/GS66508T Embedded Die Package Advanced Packaging Essentials

This is an Advanced Packaging Essentials of the GaN Systems GS66508T and GS66508B 650 V E-mode GaN transistor embedded die package technology. Each of the GS66508T and GS66508B components is an enhancement mode GaN-on-silicon power transistor and uses embedded die package technology. The power transistor die is fully embedded in a two-layer printed wiring board (PWB).
