Patent number: 10979095Abstract: A matching system of a communication device that incorporates teachings of the present disclosure may include, for example, a controller that executes instructions facilitating selection of a subset of usage scenarios according to a usage condition of a communication device. An impedance circuit is adjusted based on a subset of different tuning scenarios corresponding to the subset of usage scenarios to facilitate an impedance match to an antenna of the communication device. A group of operational parameters is obtained for each tuning scenario change between the subset of different tuning scenarios. Multiple operational parameters obtained at each of the subset of different tuning scenarios at different times are processed for each tuning scenario and a tuning scenario is selected based on a determination as to which of the processed operational parameters correlates with a predetermined performance goal. Additional embodiments are disclosed.Type: GrantFiled: August 30, 2019Date of Patent: April 13, 2021Assignee: NXP USA, Inc.Inventors: Carsten Hoirup, Keith Manssen, Matthew Russell Greene

Patent number: 10700719Abstract: A system that incorporates teachings of the present disclosure may include, for example, determining an operational criteria associated with a modulation type of a signal modulation. A single write command is generated for applying a group of tuning steps to a matching network of a mobile communication device. The group of tuning steps are determined according to the operational criteria associated with the modulation type of the signal modulation. The single write command is transmitted to a switch controller coupled to the matching network for adjusting settings of the group of switches according to the group of tuning steps to generate a desired tuning value without multiple write commands. Additional embodiments are disclosed.Type: GrantFiled: July 16, 2019Date of Patent: June 30, 2020Assignee: NXP USA, Inc.Inventors: Matthew Greene, Carsten Hoirup, Keith Manssen
