Abstract
A radio frequency (RF) thermal isolator and method of manufacture for same. According to one embodiment, the RF thermal isolator includes a first transmission line; a second transmission line of nominally the same dimensions as the first transmission line and axially aligned with the first transmission line, wherein the ends of the transmission lines are separated by a gap having a width that is a very small fraction of the center operating wavelength of the transmission lines; and an electrically conductive sleeve electrically attached to the end of the first transmission line and surrounding the end of the second transmission line and separated from the second transmission line by a gap having a width that is a very small fraction of the center operating wavelength of the transmission lines; wherein the sleeve extends along the second transmission line from the end of the first transmission line for a distance of nominally 1/4 of the center operating wavelength of the transmission lines.
