摘要： A radio frequency system may generate a first signal within a first band and a second signal within a second band for simultaneous transmission. The transceivers may receive a third signal within the first band and a fourth signal within the second band. Antennas may simultaneously wirelessly transmit the first signal and the second signal and wirelessly receive the third signal and the fourth signal. Analog signal processing circuitry elements may operate on the first signal or the second signal, or both. A controller may receive an indication of operating conditions of the radio frequency system and control the phase shifters disposed between at least two of the analog signal processing circuitry elements to reduce an amount of intermodulation distortion occurring on the third signal or the fourth signal, or both.

摘要： Electronic devices may include antenna structures. The antenna structures may form an antenna having first and second feeds at different locations. Transceiver circuitry for transmitting and receiving radio-frequency antenna signals may be mounted on one end of a printed circuit board. Transmission line structures may be used to convey signals between an opposing end of the printed circuit board and the transceiver circuitry. The printed circuit board may be coupled to an antenna feed structure formed from a flexible printed circuit using solder connections. The flexible printed circuit may have a bend and may be screwed to conductive electronic device housing structures using one or more screws at one or more respective antenna feed terminals. Electrical components such as an amplifier circuit and filter circuitry may be mounted on the flexible printed circuit.

摘要： A user equipment (UE) comprises a radio having TX and RX paths that include a duplexer, thus facilitating a full-duplex mode. The radio may also have TX and RX paths that exclude the duplexer, and which thus facilitate a half-duplex mode. The UE may be configured to autonomously and opportunistically switch from the full-duplex mode (the paths that include the duplexer) to the half-duplex mode (the paths that exclude the duplexer) when the UE desires to avoid the path loss caused by the duplexer, e.g., to temporarily receive with greater sensitivity and/or transmit with more power, during poor channel conditions. At other times the UE may autonomously decide to remain in full-duplex mode to achieve reduced transmission time, e.g., during time-critical communications such as VoLTE. The UE may autonomously determine whether to use full or half-duplex mode, i.e., without requiring any coordination with network-side devices.

摘要： Methods and devices useful in concurrently receiving and supporting Wireless Fidelity (Wi-Fi) and Long Term Evolution Licensed Assisted Access (LTE-LAA) wireless data signals are provided. By way of example, an electronic device includes a network interface configured to allow the electronic device to communicate over one or more channels of a wireless network, and a transceiver configured to transmit data and to receive data over the one or more channels. The transceiver is configured to receive licensed cellular signals and unlicensed cellular signals over the one or more channels.

摘要： An electronic device may include an antenna, a transceiver, and a low noise amplifier module that amplifies receive signals from the antenna to the transceiver circuitry in a first configuration and passes transmit signals from the transceiver to the antenna in a second configuration. The low noise amplifier module may include a first switching circuit coupled to the antenna, a second switching circuit coupled to the transceiver, at least one low noise amplifier coupled between the first and second switching circuits, and a transmit bypass path coupled between the first and second switching circuits. The transceiver may be located in a first electronic device region, whereas the low noise amplifier module and the antenna may be located in a second region. The low noise amplifier module may help compensate for signal loss between the first and second regions and allow for transmit signals to pass to the antenna.

摘要： An electronic device may include processing circuitry having a first impedance coupled to a first circuit board, where the electronic device uses the processing circuity to generate one or more radio frequency signals. The electronic device may also include power circuitry to amplify the one or more radio frequency signals, where the power circuitry is coupled to a second circuit board. An interposer may be disposed between the first circuit board and the second circuit board. The interposer may include a via structure having a characteristic impedance to match the first impedance and the second impedance, where the via structure may transmit the one or more radio frequency signals through the interposer between the processing circuitry and the power circuitry.
