Abstract
A surface mount technology ('SMT') apparatus for use in routing radio frequencies ('RF') between cavities that require a high level of isolation on a single printed circuit board (“PCB”). The SMT part is attached to the PCB over a stripline-ready trace which transitions to microstrip before and after the SMT stripline part to maintain consistent characteristic impedance. When presented with a high isolation need between two cavities using microstrip transmission lines, the proposed stripline SMT apparatus under the isolation wall will tend to provide the necessary isolation. The present invention provides a repeatable and reliable interconnect while improving the electrical match between the two cavities. Furthermore, the invention removes the costs associated with manually forming and soldering cables between PCBs.
