1. A method for configuring a differential transmission having a switch, the method comprising:
connecting a first switch in series to a first transmission line including a first distribution element having a first impedance, the first switch being disposed between a first end of the first transmission line and a second end of the first transmission line;
connecting a second switch in series to a second transmission line including a second distribution element having a second impedance, the second switch being disposed between a first end of the second transmission line and a second end of the second transmission line;
connecting a third switch between a second terminal of the first switch and a first terminal of the second switch; and
connecting a fourth switch between a first terminal of the first switch and a second terminal of the second switch,
wherein a second pair of the third and fourth switches are connected in a cross-coupled pair to cancel or offset off-capacitance of a first pair of the first and second switches, and
wherein a switch block, including the first to fourth switches, is controlled to have one of states including an open state, a 0° phase state, a 180° phase, and a short state.
