SMA Edge Card and Edge Mount RF Coaxial Connectors and SMA Rotary Joint Connectors

I have just finished uploading some of the most popular SMA (18 GHz) SMA Edge Card Connectors for 0.093", 0.063", 0.042", and 0.031" thick PCBs. These contacts all require soldering to the PCB but have very good performance since they are microstrip edge launch type connections that reduce Signal Integrity (SI) problems at RF frequencies.


I also uploaded the popular 4-pin and more recent newer press-fit 2-pin SMA Edge Mount RF Coaxial Connectors. The traditional 4-pin types are soldered in and the press fit 2-pin types allow for faster manufacturing processes.


In addition to those, I have uploaded some very uncommon slip-ring type SMA connectors that are press-fit, vertical soldered, and right-angle soldered connections. These type of connectors are used where there is a twisting or rotating motion for an antenna that supplies a constant and consistent RF connection without interruption typical in switching. The 'rotary joint' is common in RADAR applications such as linear phased arrays used in marine radar applications.


Please LIKE and comment on what other types of RF connectors or devices that you would like me to model. Thank you !
