Classification: CPC H | IPC H

Claim 7:
8. A diversity circuit configured to receive a third radio frequency signal in a first communication band in response to reception of a first radio frequency signal in the first communication band in a primary circuit, and configured to receive a fourth radio frequency signal in a second communication band in response to reception of a second radio frequency signal in the second communication band in the primary circuit, the primary circuit being configured to transmit and receive the first radio frequency signal and the second radio frequency signal, the diversity circuit comprising:
a first input terminal, a third reception terminal and a fourth reception terminal;
a first switch comprising a first selection terminal, a second selection terminal, and a first common terminal connected to the first input terminal, the first switch being configured to selectively connect the first common terminal to the first selection terminal and to the second selection terminal;
a first reception path connecting the first selection terminal and the third reception terminal, the first reception path being configured to pass the third radio frequency signal from the first input terminal to the third reception terminal via the first selection terminal; and
a second reception path connecting the second selection terminal and the fourth reception terminal, the second reception path being configured to pass the fourth radio frequency signal from the first input terminal to the fourth reception terminal via the second selection terminal, wherein:
when the first radio frequency signal and the second radio frequency signal are simultaneously received, the first switch is configured to connect the first common terminal to the first selection terminal and to the second selection terminal, and
when the first radio frequency signal is simultaneously received with transmission of the second radio frequency signal, the first switch is configured to connect the first common terminal to the first selection terminal and to the second selection terminal,
wherein the first switch is not connected to the primary circuit.
