Abstract: Power module semiconductor packages that contain a flexible circuit board and methods for making such packages are described. The semiconductor package contain a flexible circuit board, a conductive film on a first portion of the upper surface of the flexible circuit board, a land pad on a second portion of the upper surface of the flexible circuit board, a heat sink on a portion of the bottom surface of the flexible circuit board, a passive component, a discrete device, or an IC device connected to a portion of the conductive film, and a lead of a lead frame connected to the land pad. These packages can have a high degree of design flexibility of the layout of the package and simpler routing designs, reducing the time to design the packages and reducing the costs of the packages. Other embodiments are also described.

Abstract: In an embodiment, a receiver includes an antenna configured to receive a communication frame. The communication frame may include an acquisition code symbol sequence, which in turn may include a plurality of acquisition code symbols. In an embodiment, an acquisition code symbol includes a subcode sequence having a plurality of subcodes. A receiver also may include a correlation calculator coupled to the antenna. The correlation calculator may be configured to determine a correlation between the subcodes of the received communication frame and a stored version of the subcodes. The correlation may be used in determining a timing offset for further processing of the communication frame.
