Abstract:
1. An electronic device, comprising: adjustable radio-frequency circuitry and antenna structures that are operable in a plurality of different modes; radio-frequency transceiver circuitry that transmits and receives radio-frequency signals through the adjustable radio-frequency circuitry and antenna structures; and satellite navigation system receiver circuitry that receives satellite navigation signals through the adjustable radio-frequency circuitry and antenna structures, wherein a phase offset is imposed on the received satellite navigation signals by the adjustable radio-frequency circuitry and antenna structures when switching between the different modes and wherein the satellite navigation system receiver circuitry uses at least one compensating phase offset value to compensate the received satellite navigation system signals for the imposed phase offset, and wherein the satellite navigation system receiver circuitry includes a multiplexer having a plurality of inputs and an output and further includes a plurality of storage elements each of which provides a respective compensating phase offset value to a respective one of the plurality of inputs.
