Patent number: 7424039Abstract: A method and apparatus for processing multiple signals at a common frequency fed through a single radio frequency (RF) cable with or without one or more amplifiers and utilized for either forward or reverse link transmissions. The invention enables a single power amplifier to amplify multiple RF signals that occupy a common frequency channel and after amplification splitting these signals into amplified copies of the originals. The amplified signals may be sent to different antenna ports to illuminate different base station sectors if required. The signal splitting function is performed at the antenna masthead such that this method reduces the number of feeder cables running up the antenna tower by a factor of N, where N is the number of common frequency signals (e.g., the number of sectors) amplified by the single power amplifier.Type: GrantFiled: August 19, 2003Date of Patent: September 9, 2008Assignee: Nortel Networks LimitedInventors: Peter Deane, Abdelgader Legnain, Marthinus Da Silveira, Neil McGowan

Patent number: 7327541Abstract: A two-terminal ESD protection structure formed by an arrangement of five adjacent semiconductor regions (112, 114, 116, 118, and 120) of alternating conductivity type provides protection against both positive and negative ESD voltages. The middle semiconductor region electrically floats. When the two terminals (A and K) of the ESD protection structure are subjected to an ESD voltage, the structure goes into operation by triggering one of its two inherent thyristors (170 and 180) into a snap-back mode that provides a low impedance path through the structure for discharging the ESD current.Type: GrantFiled: June 22, 2004Date of Patent: February 5, 2008Assignee: National Semiconductor CorporationInventors: Albert Z.

Patent number: 6973225Abstract: The techniques of the present invention are directed towards setting a photonic device into a groove of a substrate, which is then attached to the chip sub-assembly in a way that the resulting optoelectronic package has a low profile and the interconnects between the photonic device and the semiconductor chip are short. The technique involves partially etching a groove in a substrate to allow for positioning of a photonic device within the groove. The photonic device is connected to the chip sub-assembly through interconnects that extend through the thickness of the substrate. The photonic devices are placed on their sides so that the active facets are perpendicular to the main axis of the chip sub-assembly. In this configuration, the optical fibers can be positioned parallel to the CSA top surface, ensuring a low module profile in the process.Type: GrantFiled: June 6, 2002Date of Patent: December 6, 2005Assignee: National Semiconductor CorporationInventors: Luu Thanh Nguyen, Ken Pham, Peter Deane, William Paul Mazotti, Bruce Carlton Roberts, Hau Thanh Nguyen, John P.

Publication number: 20050215288Abstract: The present invention allows transmission of multiple signals between masthead electronics and base housing electronics in a base station environment. At least some of the received signals from the multiple antennas are translated to being centered about different center frequencies, such that the translated signals may be combined into a composite signal including each of the received signals. The composite signal is then sent over a single feeder cable to base housing electronics, wherein the received signals are separated and processed by transceiver circuitry. Prior to being provided to the transceiver circuitry, those signals that were translated from being centered about one frequency to another may be retranslated to being centered about the original center frequency.Type: ApplicationFiled: March 26, 2004Publication date: September 29, 2005Applicant: NORTEL NETWORKS LIMITEDInventors: Steve Beaudin, Keith Edwards, Xiaoyun Hu, Peter Deane
