1. A switched line phase shifter comprising:
a first twist comprising at least a first cavity and a second cavity, the first cavity and the second cavity having at least two respective shapes, the first cavity and the second cavity opening from at least one of a first X1-Y1 surface of a metal block and an opposing second X2-Y2 surface of the metal block;
a second twist comprising at least a third cavity and a fourth cavity, the third cavity having the shape of the second cavity, the fourth cavity having the shape of the first cavity, the third cavity and the second cavity opening from at least one of the first X1-Y1 surface of the metal block and the opposing second X2-Y2 surface of the metal block;
a first connecting cavity coupling electro-magnetic radiation propagating along an X axis between the first twist and the second twist, wherein the first twist, the second twist, and the first connecting cavity open from at least one of the first X1-Y1 surface of the metal block and the opposing second X2-Y2 surface of the metal block; and
at least one metal cover attached to at least the first X1-Y1 surface of the metal block.
