1. A radio frequency (RF) switch, comprising:
a first RF transmission line and a second RF transmission line that are capacitively coupled to each other;
a third RF transmission line having a signal trace that is electrically isolated from the first and second RF transmission lines; and
a conductive rod that is coupled to ground, the conductive rod defining a rotational axis of the RF switch,
wherein the RF switch is configured such that by rotating the RF switch around the conductive rod, any two of the first, second and third RF transmission lines are capacitively coupled to each other while leaving a remaining one of the first, second and third RF transmission lines electrically isolated from all other RF transmission lines, and
wherein the remaining one of the first, second and third RF transmission lines is electrically connected to ground.
