Patent number: 7283793Abstract: A transceiver front end circuit includes an antenna terminal capable of being coupled to an antenna. A first balun circuit has a single input that is coupled to the antenna terminal, and a pair of balanced outputs coupled to a corresponding pair of balanced receiver inputs. The first balun circuit matches an input impedance of the pair of balanced receiver inputs and substantially phase shifts the input reflection coefficient of the pair of balanced receiver inputs by about 180-degrees. A second balun circuit has a single output coupled to the antenna terminal and a pair of balanced inputs coupled to a corresponding pair of balanced transmitter outputs. The second balun circuit matches an output impedance of the pair of balanced transmitter outputs and substantially phase shifts the output reflection coefficient of the pair of balanced transmitter outputs by about 180-degrees. The first balun circuit and the second balun circuit can be contained within a single package.Type: GrantFiled: September 30, 2002Date of Patent: October 16, 2007Assignee: Broadcom CorporationInventor: Tom McKay

Publication number: 20060010876Abstract: In a method for operating a gas turbine centre in the vicinity of the group nominal full-load conditions, the cooling of the working fluid before and/or during the compression is set in such a way that the respectively attainable full-load power is above the current power. Rapid power demands can therefore be rapidly satisfied by an increase in the turbine inlet temperature or by opening an adjustable inlet guide vane row, whereas the control of the cooling effect, which has a tendency to be more sluggish, is employed to adjust the full-load operating point.Type: ApplicationFiled: August 11, 2005Publication date: January 19, 2006Inventors: Jurgen Hoffmann, Tom McKay, Nikolaus Kurz, Tobias Spitzmuller
