The TLF40 from Signal Microwave are 2.92 mm Top Launch Connectors that operate up to 40 GHz. They are designed to offer edge launch type performance anywhere on the board. These 50-Ohm connectors can transition to a microstrip or grounded coplanar line on the top layer of the board. They can be mounted with compression contact mechanism and therefore, no soldering is required. Upon integrating these connectors into the board, the signal does not need to travel through the board vias. These connectors are available in 303 stainless steel housing with neoflon and beryllium copper center conductor.
