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.
