    摘要: An RF/IPD package with improved thermal management is described. The IPD substrate is attached to a system substrate with a thin RF chip mounted in the standoff between the IPD substrate and the system substrate. RF interconnections are made between the top of the RF chip and the bottom of the IPD substrate. Heat sinking is provided by bonding a heat sink layer on the RF chip to a heat sink layer on the system substrate. The heat sink may also serve as a ground plane connection. Combinations of other types of integrated devices may be fabricated using this approach.

    摘要: 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.

    摘要: Balun transformers are described wherein multiple transformer loops are implemented in a stacked design with the primary and secondary loops overlying one another. By aligning the loops in a vertical direction, instead of offsetting the loops, the area of the device is reduced. Multiple transformer loops are nested on each level, and the transformer loops on a given level are connected together using a crossover located on a different level.
