Publication number: 20060217102Abstract: The specification describes an integrated passive device (IPD) designed to allow implementation of cellular RF and Wi-Fi RF in a single hand held device. To address the problem of RF interference a thin film RF high rejection bandpass filter is formed in an IPD implementation. The IPD implementation preferably uses silicon as the substrate material. This allows the thin film RF high rejection bandpass filter to be made using silicon processing technology, and thus produce low cost filters that still meet stringent performance requirements demanded due to the co-existing RF units. In preferred embodiments of the invention, wafer level processing using silicon substrates adds to the cost effective manufacture of the highly functional IPDs.Type: ApplicationFiled: March 22, 2005Publication date: September 28, 2006Inventors: Yinon Degani, Yu Fan, Charley Gao, Kunquan Sun, Liguo Sun, King Tai

Patent number: 6734539Abstract: The specification describes an MCM package which contains both a digital MCM and an RF MCM in a stacked configuration. The package contains means for isolating RF signals from digital signals. In one case the digital MCM substrate is attached to the system substrate and the RF MCM substrate is attached to the digital MCM substrate. Solder bumps are used for attachment in an arrangement resembling a BGA. For high density packages, at least the digital MCM comprises stacked IC chips. In the embodiment with the RF MCM substrate on the top of the stack, Passive Through Interconnections (PTIs) are made through the digital MCM substrate, and electrically isolated therefrom. The passive through interconnections are made through the solder bumps between boards and interconnected using a passive (with respect to the digital MCM board) through hole. Both the RF ground and the RF input can be isolated using PTIs. For additional isolation, the solder bumps comprising the PTIs are shielded with a Faraday cage.Type: GrantFiled: September 26, 2001Date of Patent: May 11, 2004Assignee: Lucent Technologies Inc.Inventors: Yinon Degani, Thomas Dixon Dudderar, Liguo Sun, Meng Zhao
