Abstract: An electronic device may be provided with wireless circuitry that includes a transceiver. The transceiver may include a first signal path and a second signal path extending parallel to the first signal path. The first signal path may include a first chain of gain stages and a first inductive matching network. The second signal path may include a second chain of gain stages and a second inductive matching network. The first inductive matching network may be magnetically coupled to the second inductive matching network. The first and/or second signal path may include one or more crossovers that invert a polarity of the signals on the signal paths. The crossovers may help to mitigate the effects of the magnetic coupling between the first and second signal paths while allowing for minimal spatial separation between the signal paths.

Abstract: Wireless circuitry can have an antenna coupled to a receiving amplifier. The receiving amplifier may be coupled to a local feedback loop configured to reduce the gain of the receiving amplifier for suppressing the signal power when receiving a large input signal. The local feedback loop can include a detector and a feedback controller. The detector may have an input coupled to the receiving amplifier and can output a detected signal. The feedback controller may receive the detected signal and output a corresponding control signal. The control signal can be used to reduce the gain of the receiving amplifier by adjusting one or more components within or coupled to the receiving amplifier. Suppressing large input signals in this way presents no additional parasitic loading to the downlink path and can thus provide overvoltage protection without degrading receiver performance.

Abstract: An electronic device may include wireless circuitry with a processor, a transceiver circuit, a front-end module, and an antenna array having multiple antennas. The front-end module may include radio-frequency splitter-combiner circuitry that splits radio-frequency signals from a single port into multiple radio-frequency signals at multiple split ports and/or combines radio-frequency signals from the multiple ports into radio-frequency signals at the single combined port. The radio-frequency splitter-combiner may include adjustable components such as switches, adjustable inductors, and/or adjustable capacitors that place the radio-frequency splitter-combiner in different configurations based on whether or not there are inactive split ports coupled to inactive antennas. This enables improved impedance matching for active split ports even while one or more split ports remain inactive, thereby reducing power loss in this mode of operation.
