[May 16, 2013] Freescale Semiconductor Assigned Patent Tweet (Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., May 16 -- Freescale Semiconductor, Austin, Texas, has been assigned a patent (8,442,456) developed by five co-inventors for a "wireless communication unit, integrated circuit and method of power control therein." The co-inventors are Norman Beamish, Cork, Ireland, Conor O'Keeffe, Cork, Ireland, Patrick Pratt, Mallow, Ireland, David Redmond, Cork, Ireland, and Jacques Trichet, Cugnaux, France. The abstract of the patent published by the U.S. Patent and Trademark Office states: "A wireless communication unit comprises a transmitter having a power amplifier and a feedback path operably coupled to the power amplifier. The feedback path comprises a coupler for feeding back a portion of a signal to be transmitted and a detector for detecting a power level of the fed back signal. A controller provides a ramp signal to the power amplifier that controls an amplitude characteristic of the signal to be transmitted. Averaging logic is operably coupled to the detector and arranged to average the detected power level over a first period. Comparison logic is operably coupled to the averaging logic and arranged to compare the average detected power level with a reference value. The controller is operably coupled to the comparison logic and arranged to scale a ramp signal applied to the power amplifier in response to the comparison." The patent application was filed on Aug. 9, 2007 (12/671,233).
