ABSTRACT:
Coax to microstrip orthogonal launchers that use a compressible fuzz button center conductor as a solderless interconnect. The launcher comprises a coaxial connector having a center conductor that contacts a compressible fuzz button interconnect. In certain embodiments, the fuzz button interconnect directly contacts one end of a microstrip line. In another embodiment, the microstrip line is formed on a curved microstrip circuit board, and the fuzz button interconnect contacts a pin that has a thin metal tab that is adhesively secured to the one end of the microstrip line. In all embodiments, a second coaxial connector has a center conductor that contacts the opposite end of the microstrip conductor line. The present invention eliminates need for precise soldering by using the fuzz button interconnect to create a solderless compression contact between the coaxial connector and the microstrip line. The present invention provides a simple way to vertically launch an RF signal onto microstrip transmission line from a coaxial cable and operates at frequencies up to 18 GHz.
