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.

Systems and methods for mitigating intermodulation effects

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 front end module having an arbiter device that controls one or more gain stages to selectively amplify the Wi-Fi and LTE-LAA signals.

Low noise amplifier arbiter for license assisted access systems

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.
