Abstract: A communication device has multiple antennas in an antenna array, and applies the same input power to each antenna. A controller of the communication device instructs phase shifters to form a first subarray with a first pair of the antennas and a second subarray with a second pair of the antennas. The controller causes the first subarray to generate a first beam and causes the second subarray to generate a second beam, wherein the first beam combines in phase with the second beam to generate a coarse beam. The coarse beam may have increased beam width while exhibiting decreased peak gain loss.

Abstract: Techniques for implementing and/or operating a radio frequency system, which includes a logic board that outputs an analog electrical signal indicative of data to be wirelessly transmitted from the radio frequency system and a remote head. The remote head includes an antenna that generates an electromagnetic wave to facilitate wirelessly transmitting the data, an antenna integrated circuit implemented using a first semiconductor manufacturing technique, in which the antenna integrated circuit amplifies the analog electrical signal to generate a first amplified analog electrical signal, and a remote front-end integrated circuit coupled between the antenna integrated circuit and the antenna. The remote front-end integrated circuit is implemented using a second semiconductor manufacturing technique different from the first semiconductor manufacturing technique and amplifies the first amplified analog electrical signal based on a target output power of the antenna to generate a second amplified analog electrical signal indicative of the data.

Abstract: Systems, methods, and devices are provided for correcting compression distortion of wireless signals due to variations in operation parameters of the radio frequency system. The method may include using circuitry to generate a reference signal that is not pre-distorted by a processing block. The method may involve receiving an envelope signal representative of a signal being transmitted by a transceiver. The method may also involve determining a first peak-to-average ratio of the envelope signal and receiving a second peak-to-average ratio of the reference signal. The method may additionally involve determining a difference between the first peak-to-average ratio and the second peak-to-average ratio. The method may also include adjusting a gain of an amplifier of the transceiver based on the difference.

Abstract: A wireless electronic device may include switching circuits that perform time division duplexing by toggling between a first configuration in which radio-frequency signals received from antennas are routed to the transceivers and a second configuration in which the antennas are coupled to antenna switching circuitry. The antenna switching circuitry may receive radio-frequency transmission signals from the transceivers and route the transmission signals to a selected one of the antennas. The antenna switching circuitry may be controlled by control circuitry such as baseband circuitry and/or storage and processing circuitry on the device. The antenna switching circuitry may be controlled to accommodate antenna transmit diversity without affecting reception of radio-frequency signals, because the switching circuits that perform time division duplexing may form signal reception paths that are unaffected by the configuration of the antenna switching circuitry.

Abstract: Apparatus and methods for radio co-existence and/or component testing in wireless-enabled electronic devices. In one embodiment, a wireless-enabled electronic device (ED) is coupled to a user interface. Test personnel or other supervisory entities can execute test scripts from the user interface. Unlike prior art testing configurations, the disclosed embodiments are configured to perform testing without requiring additional equipment, configuration changes, etc. to the device being evaluated. In one exemplary case, the test scripts are configured to test various co-existence scenarios. The resulting data can be used to quickly identify problem devices via highly accurate results, as well as provide useful statistical data.

Abstract: An electronic device may include transceivers, radio-frequency front end (RFFE) circuitry, antennas, and a feedback receiver. The RFFE circuitry may include power amplifier (PA) modules that each transmits radio-frequency signals in a corresponding group of frequency bands. The modules may include power amplifiers, a band selection switch, and an antenna selection switch coupled to the band selection switch over a signal path. A radio-frequency coupler may be disposed on the signal path between the band selection switch and the antenna selection switch. A PA module may include a feedback receiver aggregation switch. The aggregation switch may be coupled to the radio-frequency coupler on its PA module and radio-frequency coupler(s) on other PA modules over feedback paths. The aggregation switch may pass coupled signals from the couplers to the feedback receiver for measurement.
