Low cost semiconductor manufacturing techniques have provided consumers with a wide range of electronic devices supporting communications according to multiple standards. These electronic devices will be deployed within many operational jurisdictions, particularly with roaming features, such as Japan, Europe, Asia-Pacific, South America and North America. However, operational compliance requirements can vary substantially with these different jurisdictions. Current electronic devices are designed, manufactured, calibrated and operated according to a specification providing compliance with broad range of operational jurisdictions despite the performance limitations this applies in many of the operational jurisdictions. Accordingly, there is provided a method of dynamically configuring the electronic device based upon a geographically based determination of the operational jurisdiction from global navigation systems data received by the electronic device. Based upon the determined operational jurisdiction, the operational parameters of a device's communication interfaces are adjusted for improving performance and efficiency of the device within these jurisdictions.

Jurisdiction based parameter setting for wireless transceivers

A system improve amplifier efficiency of operation relative to that of an amplifier with fixed biasing and fixed matching conditions receives a power level and an indicator of amplifier operation. The indicator is at least one of channel, channel bandwidth, out-of band spectral requirements, spectral mask requirements, error vector magnitude, modulation rate, and modulation type. A controller generates a control signal based at least in part on the power level and the indicator to control at least one of the bias current and the matching conditions of matching circuits. The matching conditions and bias current for channels at an edge of a channel band are different from the bias current and matching conditions for channels nearer a center of the channel band.

Amplifier control systems and methods

A method is disclosed wherein a power level indicating a level of transmission power from an amplifier is provided. An indication of at least one of channel, channel bandwidth, OOB spectral requirements, spectral mask requirements, EVM, modulation rate, and modulation type is also provided. A control signal for controlling one of a bias current provided to the amplifier and a matching circuit for matching an output port of at least a stage of the amplifier is generated, the control signal determined in dependence upon the power level and the at least an indication. Then the one of the bias current and the matching circuit is adjusted in accordance with the control signal.
