Abstract: The ABB blocks 332, 334, 336, and 318 are configured to process the I/Q signals corresponding to the first or the second HB independently or the I/Q signals corresponding to the LB in cooperation by two. In detail, the first ABB I block 332 and the first ABB Q block 334 operate independently in the 3G/4G mode but they are configured to process the I signal (or Q signal) of the LB in the 2G mode. Likewise, the second ABB Q block 336 and the second ABB I block 318 operate independently in the 3G/4G mode but they are configured to process the Q signal (or I signal) of the LB in the 2G mode. The first ABB I/Q blocks 332 and 334 and the second ABB I/Q blocks 336 and 318 are arranged symmetrically to processing the I/Q signals cooperatively in the 2G mode. In detail, the second ABB Q block 336 is arranged close to the first ABB Q block 334 such that the capacitor regions included in the first ABB I/Q blocks 332 and 334 are connected to each other and the capacitor regions included in the second ABB I/Q blocks 336 and 338 are connected to each other.
