Abstract: A system and method of circuit board and device construction provide an RF testing connection for thin devices that lack space between their printed circuit board (PCB) and their housing for a test connection. In particular, in designs wherein the device PCB lies against the rear housing of the device, the use of a dedicated test connector on the back of the main PCB is problematic, but a circuit configuration is provided such that a removable test connection can be used without affecting the operation of the device or the configuration of the PCB itself.

Abstract: A method and system selects an antenna for signal propagation within a wireless communication device having multiple antennas. A transfer switch controller identifies an operating mode being initiated on the wireless communication device. The transfer switch controller configures a dynamic transfer switch based on the operating mode initiated to support propagation of each available type of communication signal. In addition, the transfer switch controller utilizes a pre-established priority of each available type of communication signal to select the appropriate antenna. The transfer switch controller communicatively connects, utilizing the configured dynamic transfer switch, each of at least one transceiver associated with the operating mode initiated to a specific antenna, where each transceiver supports propagation of a specific type of communication signal.

Abstract: A method and system provides a multiple input multiple output (MIMO) antenna arrangement in a wireless communication device. A first antenna element and a second antenna element co-located within a same antenna volume are respectively coupled to first and second antenna feeds proximate to a base perimeter segment of a device chassis. The first antenna feed is at a pre-calculated distance from the second antenna feed. The second antenna element, a first MIMO antenna, is coupled to an antenna ground positioned proximate to the first antenna feed and at a pre-determined distance from the second antenna feed. A third antenna element operating as a second MIMO antenna is placed proximate to a top perimeter segment of the device chassis. The antenna arrangement achieves (a) low correlation between the MIMO antennas and (b) an acceptable or pre-determined level of antenna isolation between the first antenna element and the second antenna element.

Abstract: A method and system configures operating parameters associated with an operation of a connected accessory or second device in order to mitigate harmonic interference within an operating frequency band of a wireless communication device (WCD). In response to a connection between the WCD and the second device via a physical communications interface, Accessory Authentication and Configuration (AAC) logic of the WCD receives device identifying information about the second device. The AAC logic determines candidate values for each operating parameter, based on the device identifying information. The AAC logic dynamically selects a particular candidate value for each operating parameter, based on a current operating frequency band of the WCD, and an expected level of harmonic interference.

Abstract: A portable device, such as a handheld device (10), laptop device or other suitable portable device, employs an antenna beam selection structure that is coupled to a plurality of built-in antennas (12 and 14) of the portable device that have different beam angles with respect to each other. The plurality of built-in antennas are coupled to a satellite network positioning signal processing circuit (18) so that device positioning signals from a satellite network can be received and processed by the device. The plurality of built in antennas may be stationary or movable with respect to each other. A control circuit (20) is operative to control switching between each of the plurality of built in antennas based on detected signal strength, signal quality measurements, the number of positioning satellites detected by a satellite network positioning signal processing circuit or other suitable criteria.

Abstract: A mobile wireless communication device (10) having a direct conversion receiver (20) reduces spurious mixer response by predicting blockers on the received RF signal. The chopping frequency of the mixer is changed (305) dynamically in response to the prediction of blockers on the input signal to avoid the mixing the blocker with chopper spurs, thereby improving the response of the receiver. In some embodiments, the mixer is disabled momentarily (402) to verify that poor signal quality results from mixing chopper spurs with blockers. In hopping mode applications, the chopper frequency is changed only on channels having a low confidence factor (512).
