Abstract: The representative embodiments discussed in the present disclosure relate to techniques in which isolation between transmission signals and received signals in a transceiver may be maintained during downlink carrier aggregation. More specifically, in some embodiments, the transceiver may be implemented to include an electrical balance duplexer that isolates a signal component of a signal transmitted via the transceiver from a receiver signal path of the transceiver. The transceiver may also include analog interference cancellation circuitry implemented to isolate a noise component of the signal transmitted via the transceiver from the receiver signal path (e.g., from one or more downlink receiver channels). As such, the transceiver may operate using inter-band, non-contiguous downlink carrier aggregation, intra-band, non-contiguous downlink carrier aggregation, intra-band, contiguous carrier aggregation, and/or the like.

Abstract: The representative embodiments discussed in the present disclosure relate to techniques in which isolation between transmission signals and received signals in a transceiver may be maintained across a range of transceiver operating conditions, such as across range of output powers of a power amplifier of the transceiver. More specifically, an electrical balance duplexer may be implemented to include an adaptive power equalizer and a power equalizer control such that the attenuation of the electrical balance duplexer may be adjusted based on the transceiver operating conditions. For instance, a method may be employed to determine the output power of the power amplifier and to adjust the attenuation of the adaptive power equalizer based in part on the output power to maintain isolation between the transmission signals and the received signals.

Abstract: Portable user devices are provided that communicate wirelessly with base stations. A user device may include a transceiver, a power amplifier, a voltage supply, and a global positioning system (GPS) unit. The device may transmit signals at a certain transmit power to a neighboring base station. The device may log the time spent transmitting at each power level. Each data point may be tagged with the current location of the device. The logs of each device may be aggregated by a power optimization server. The power optimization server may calculate optimum power settings for each region and for each type of device. A region may be any desirable size ranging from the size of a single cell to an entire continent. Device users may download updated optimum settings. A device may automatically detect and select the optimum transmit power setting during operation depending on its current location.

Abstract: Portable electronic devices are provided with wireless circuitry. The wireless circuitry may include one or more sets of radio-frequency power amplifiers. The radio-frequency power amplifiers are used to amplify radio-frequency signals that are transmitted by the portable electronic devices. Each power amplifier may have multiple gain mode settings. Gain stages within the power amplifiers may be selectively enabled in accordance with the gain mode settings. When a higher level of gain is required, all of the gain stages may be enabled. When a lower level of gain is required, some of the gain stages may be disabled to conserve power. An adjustable power supply may be used to provide an adjustable power supply voltage to the power amplifiers. The adjustable power supply voltage can be reduced when it is desired to minimize power consumption at a particular gain mode setting. Gain mode and power supply settings may be adjusted simultaneously.

Abstract: Electronic devices such as cellular telephones may include wireless communications circuitry such as power amplifiers. Power amplifiers, transmission lines, and other circuit associated the power amplifiers may generate different amounts of heat depending on their operating frequency. High-heat-producing power amplifiers may be biased at lower bias voltages than low-heat-producing amplifiers to equalize temperatures and enhance performance. Performance may also be optimized by placing power amplifiers on a printed circuit board so that the high band amplifiers are placed in regions that can dissipate more heat, whereas low band amplifiers are placed in regions that dissipate less heat.

Abstract: A portable user device may provide Global Positioning System (GPS) services. The device may include a GPS unit. The GPS unit may provide accurate information about the current position, direction, and speed of the device. A user may use the device to perform tasks. Certain tasks may generate excess heat that causes the GPS unit to produce erroneous data. Methods can be used to acquire accurate data samples that are associated with the respective tasks. The device may wait for a period of time after the start of a task before acquiring a GPS sample. The device may also buffer GPS samples and to take the most recent buffered sample as the acquired GPS sample. The device may take a GPS sample immediately after the start of a task, before error starts to arise. GPS samples may be buffered and used to calculate an extrapolated data sample value.
