Abstract: Systems, methods, and devices are provided for detecting the presence of an object near an electronic device. A radio frequency (RF) system of an electronic device may include a first circuit that includes one or more transmission paths for transmitting a reference signal external to the electronic device. The RF system may include a second circuit that includes one or more receiving paths for receiving a reflection signal based on the reference signal. The RF system may also include a processor that may instruct the RF system to perform a comparison between the reference signal and the reflection signal, determine whether the object is in proximity based at least in part on whether comparison results exceed a comparison threshold, and decrease power output by the RF system below the comparison threshold.

Abstract: Systems and methods for improving communication reliability of a radio frequency system that includes an antenna integrated circuit, which includes an antenna amplifier unit that outputs a first analog electrical signal that indicates data, a transceiver integrated circuit implemented using a first semiconductor manufacturing technique, in which the transceiver integrated circuit includes a transceiver amplifier unit that outputs a second analog electrical signal that indicates the data, and a driver integrated circuit implemented using a second semiconductor manufacturing technique. The driver integrated circuit includes an intermediate amplifier, which outputs a third analog electrical signal that indicates the data, and intermediate routing circuitry, which routes the first analog electrical signal to the intermediate amplifier and the third analog electrical signal to the transceiver integrated circuit during reception and routes the second analog electrical signal to the intermediate amplifier and the third analog electrical to the antenna integrated circuit during transmission.

Abstract: An electronic device may be provided with a phased antenna array controlled by phase and magnitude controllers within an integrated circuit. The array may be formed on antenna layers and the integrated circuit may be mounted to transmission line layers of a dielectric substrate. A ground plane may separate the transmission line layers from the antenna layers. A connector may be mounted to the surface of the transmission line layers and may be coupled to the integrated circuit using conductive traces. A passive resonator may be formed in the antenna layers and may include conductive structures that resonate at one-quarter of the effective wavelength of operation of the array to form an open circuit impedance for surface currents generated on the ground plane by the array. This may serve to block the surface currents from scattering at an edge of the ground plane and leaking onto the integrated circuit.

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: A wireless electronic device may be used to communicate using multiple wireless standards in adjacent frequency bands. The wireless standards may include Wi-Fi® and cellular standards such as Long Term Evolution (LTE). The wireless electronic device may be provided with wireless communications circuitry that handles Wi-Fi® and cellular signals in adjacent frequency bands such as the Wi-Fi® 2.4 GHz frequency band and LTE bands 38 and 40. The wireless communications circuitry may include a triplexer interposed between transceiver circuitry and an antenna. The triplexer may be used to handle radio-frequency signals in adjacent frequency bands by separating the radio-frequency signals into signals associated with each frequency band. The triplexer may include filters that each pass signals in a respective one of the frequency bands between the transceiver circuitry and the antenna.

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 translation: 无线电子设备可以包括通过在其中从天线接收的射频信号被路由到收发器的第一配置和天线耦合到天线切换电路的第二配置之间切换来执行时分双工的切换电路。 天线切换电路可以从收发机接收射频传输信号，并将传输信号路由到选定的一个天线。 天线切换电路可以由诸如设备上的基带电路和/或存储和处理电路之类的控制电路来控制。 可以控制天线切换电路以适应天线发射分集而不影响射频信号的接收，因为执行时分双工的切换电路可以形成不受天线切换电路的配置影响的信号接收路径。
