1. Wireless communications circuitry comprising:

  • transceiver circuitry comprising a first transceiver circuit and a second transceiver circuit, wherein the first and second transceiver circuits communicate using different communications protocols and a common radio-frequency frequency band;

    an antenna that handles radio-frequency signals in the common radio-frequency frequency band; and

    a radio-frequency coupler comprising an input and first and second outputs, wherein when the wireless communications circuitry is operated in a first mode, the input receives radio-frequency signals from the antenna and simultaneously provides corresponding first and second reduced-power versions of the received radio-frequency signals to the first and second outputs, respectively, wherein the first reduced-power version of the received radio-frequency signals is received by the first transceiver circuit, and wherein the second reduced-power version of the received radio-frequency signals is received by the second transceiver circuit.
