1. An integrated circuit (IC) comprises:

  • a first radio frequency (RF) section coupled to;

    convert a first inbound RF signal into a first inbound symbol stream when enabled; and

    convert a first outbound symbol stream into a first outbound RF signal when enabled;

    a second RF section coupled to;

    convert a second inbound RF signal into a second inbound symbol stream when enabled; and

    convert a second outbound symbol stream into a second outbound RF signal when enabled; and

    antenna coupling matrix coupled to;

    in a first mode, couple the first RI section to a first antenna structure and couple the second RF section to a second antenna structure;

    in a second mode, couple the first RF section to the first antenna structure and to the second antenna structure; and

    in a third mode, couple the second RF section to the first antenna structure and to the second antenna structure.
