Abstract
A TEM-mode transmission line switch coupling essentially all input power at a first port to a fourth port when in its uncoupled position and coupling a predetermined significant fraction of the input power to a second port with the remainder coupled to the fourth port when in its coupled position, the switch including a relatively wide spaced parallel transmission line section with a rotatable conductive vane disposed between the parallel lines to allow coupling of power between the lines in the coupled position and inhibit such coupling in the uncoupled position.
