| 摘要 |
The invention relates to a coupler (1) and a mobile phone (25) for multiple frequency bands with a coupler (1) for coupling an output signal of a control loop (5, 10, 15, 20) back into the control loop (5, 10, 15, 20). The coupler (1) has at least two input ports (30, 35) and a common coupling port (40). The first one of the at least two input ports (30, 35) are connectable to an output port (45) of a first one of at least two control loops (5, 10, 15, 20). A second one of the at least two input ports (30, 35) is connectable to an output port (50) of a second one of the at least two control loops (5, 10, 15, 20). The at least two control loops (5, 10, 15, 20) share a common loop control (55). An input (85) of the common loop control (55) is connectable to the common coupling port (40). The coupler (1) couples signals received at the first and second one of the at least two input ports (30, 35) to the common coupling port (40). <IMAGE>
