Patent ID: 8369268

Claim:
A circuit that connects first and second wireless communications devices to a donor antenna for wireless communications, the circuit comprising: a first single-stage circulator coupled to a transmission-reception path of the first wireless communications device; a two-stage circulator coupled to the first single-stage circulator and to a transmission-reception path of the second wireless communications device; a two-way splitter coupled to the two-stage circulator and to a transmission-reception path of the donor antenna; and a second single-stage circulator coupled between the two-way splitter and the first single-stage circulator, wherein wireless transmissions of the first wireless communications device travel from the first single-stage circulator to the two-stage circulator to the two-way splitter to the donor antenna and wireless transmissions of the second wireless device travel from the two-stage circulator to the second single-stage circulator to the two-way splitter to the donor antenna, and wherein, wireless reception at the donor antenna are routed from the two-way splitter.
