摘要： 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.

摘要： An integrated RF circuit has an RF input port and an RF output port coupled to an external circuit element having known impedance such as an antenna. An RF circuit element is disposed between the RF input port and the RF output port and has a first input port and a first output port. The RF circuit element affects a signal received at the first input port and provides the affected signal to the first output port. The integrated RF circuit also has a VSWR detector circuit that measures a ratio of a characteristic of RF signals at the first input port and the first output port and that provides an indication of the ratio at a VSWR output port. The measured ratio of the characteristic is affected by an impedance of the coupling thereby providing an indication relating to the coupling.

摘要： A circuit is disclosed with an external coupling port for coupling to an external antenna, for example. The circuit has an FDD receive path including a narrowband passband filter. The circuit has a TDD receive path bypassing the narrowband passband filter but relying on a same amplifier. The circuit also has an FDD transmit path including a narrowband passband filter. The circuit has a TDD transmit path bypassing the narrowband passband filter of the FDD transmit path but relying on a same transmit amplifier. A switching configuration allows the circuit to operate in TDD mode, alternating between the TDD receive path and the TDD transmit path and in the FDD mode wherein the FDD transmit and receive paths are simultaneously coupled to the external coupling port.

摘要： A method of reducing distortion in the output of an amplifier is provided. The method comprises subtractively combining an error signals with the appropriate phase shift with input signals to be amplified. The error signal being generated by subtractively combining a fed-forward portion of the input signal with a portion of the fed-back amplified output signal, and signal processing applied to it between its generation and application to correcting the input signal in the baseband domain. The error therefore being down-converted, filtered, and up-converted in the feedback path. The filtered baseband error signal components providing inputs to a controller which adjusts active elements of the amplification and feedback path in order to minimize the distortion within the output of the amplifier.

摘要： A collector boost circuit is disclosed for providing a first voltage in a first mode of operation to a power amplifier, and another voltage in a second mode of operation to the power amplifier. The collector boost circuit uses an indicator signal derived by an RF detector to switch between the first and the second mode of operation. The another voltage is a boosted voltage greater than the first voltage and is provided when required during peak excursions to prevent amplifier clipping through a boost capacitor. The another voltage is continuous and varies in accordance with the detected peak signal amplitude.
