Patent number: 8351855Abstract: Disclosed herein are systems, apparatuses, and methods for providing a proximity coupling without Ohmic contact. Such a system includes a plurality of wireless-enabled components (WECs) that are wirelessly coupled to each other. Each WEC includes a metal-based element, a substrate, and a semiconductor layer that separates the metal-based element from the substrate. A signal is configured to be transmitted via a proximity coupling (e.g., a magnetic coupling, an electric coupling, and/or an electromagnetic coupling) between the metal-based element and the substrate without an Ohmic contact between the metal-based element and the substrate. In an example, a first subset of the plurality of the WECs is co-located on a first chip, and a second subset of the plurality of the WECs is co-located on a second chip. The first chip and the second chip may be located in a single device or in separate devices.Type: GrantFiled: September 8, 2010Date of Patent: January 8, 2013Assignee: Broadcom CorporationInventors: Jesus Alfonso Castaneda, Arya Reza Behzad, Michael Boers, Ahmadreza Reza Rofougaran, Sam Ziqun Zhao

Patent number: 8086263Abstract: Double transformer balun for maximum PA (Power Amplifier) power. A novel approach is presented herein by which conversion from a differential signal to single-ended signal may be achieved using a double transformer balun design. The secondary coils of the double transformer balun also operate as a choke for the PA supply voltage. The secondary coils can operate as an RF (Radio Frequency) trap or choke to keep any AC (Alternating Current) signal components and to pass any DC (Direct Current) components. By using a double transformer balun design, relatively thinner tracks may be employed thereby ensuring a high degree of electromagnetic coupling efficiency and high performance. Also, these relatively thinner tracks consume a relatively small amount of space on the die. The double transformer balun design also includes a matching Z (impedance) block that is operable to match the Z of an antenna or line that the PA is driving.Type: GrantFiled: February 22, 2011Date of Patent: December 27, 2011Assignee: Broadcom CorporationInventors: Jesus Alfonso Castaneda, Qiang Li, Ahmadreza (Reza) Rofougaran
