Abstract: A wireless electronic device may include antennas formed at different locations on the device. The wireless electronic device may include transceivers that are used to wirelessly communicate in different frequency bands by transmitting and receiving radio-frequency signals in the frequency bands. The transceivers may include Wi-Fi® transceivers and cellular transceivers such as Long Term Evolution transceivers. The wireless electronic device may include antenna switching circuitry interposed between the transceivers and the antennas. The wireless electronic device may include control circuitry that controls the antenna switching circuitry to ensure that radio-frequency transmissions in adjacent frequency bands are routed to different antennas. By routing radio-frequency transmissions in adjacent frequency bands to different antennas, self-interference between communications in the adjacent frequency bands may be reduced. Self-interference may also be reduced by performing time division multiplexing to isolate radio-frequency signals that are transmitted in adjacent frequency bands.

Abstract: 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.

Abstract: Systems and method to improve performance of a radio frequency system while operating in compliance with wireless transmission regulations are provided. One embodiment describes a radio frequency system including an antenna that wirelessly transmits an analog electrical signal at a transmission frequency and receives a first network signaling value from a wireless network. The radio frequency system further includes a controller that determines operational constraints on the radio frequency system based on a region of operation; determines a second network signaling value based on the operational constraints, in which the second network signaling value overrides the first network signaling value; determines operational parameters based on the second network signaling value; and instructs the radio frequency system to implement the operational parameters to facilitate the radio frequency system operating in compliance with the operational constraints.

Abstract: A test system for testing a wireless electronic device is provided. The test system may include a test host and a tester. The test host may instruct a wireless electronic device under test (DUT) to transmit radio-frequency uplink signals in selected uplink resource blocks of an uplink channel in a desired Long Term Evolution (LTE) frequency band. The tester may convey radio-frequency test data to the DUT in a selected downlink resource block of a downlink channel in the desired LTE frequency band. The DUT may measure data reception throughput values associated with the test data. The test host may compare the measured data reception throughput values to threshold data reception throughput values to characterize the radio-frequency performance of the DUT. The test system may test the radio-frequency performance of the DUT for test data in some or all downlink resource blocks of the downlink channel.

Abstract: An electronic device has wireless communications circuitry that includes transmitters and receivers. Antenna structures may be coupled to the transmitters and receivers to support radio-frequency signal transmission and radio-frequency signal reception operations. Switching circuitry such may be used to support multiple communications bands of interest. One or more low band receivers may be associated with the first switch and one or more high band receivers may be associated with the second switch. The switches can be configured in real time to switch a desired communications band into use. A diplexer may be used to simultaneously pass low bands to the first receiver and high bands to the second receiver. In this way, a data stream in the low band may be simultaneously received with a data stream in the high band.
