There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: The objective of the proposed research is to design and demonstrate three-dimensional integrated passive device (3D IPD) diplexers and three-dimensional integrated passive and active component (3D IPAC) packages with ultra-miniaturized glass substrates for radio frequency (RF) fourth generation long-term evolution (4G LTE) front-end modules (FEMs). First, high-rejection diplexers are integrated into low-loss thin glass substrates as double-side embedded thinfilm passives, interconnected with through glass vias. Second, 3D RF modules are demonstrated on ultra-thin glass substrates with double-side integration of discrete components and substrate-embedded impedance matching networks. Design and processes innovations on ultra-thin (50 -100 μm) glass substrates enable high-Q passives embedding, precise circuitry patterning and high package reliability. The proposed high-density 3D integration technology of RF passives and modules on advanced glass substrates, further extends the existing wireless communication systems towards high performance, multi-functionality and ultra-miniaturization.
