Solder the pin strip to the SMA board mount connector:
a Solder the leads on the left side of the pin strip to the center conductor of the SMA connector
as shown in the diagram below.
b Solder the leads on the right side of the pin strip to the inside of the SMA connector's frame as
shown in the diagram below. Use a small amount of solder.
Attach the second SMA board mount connector:
a Re-heat the solder connection made in the previous step, and attach the second SMA
connector, as shown in the diagram below. Note that the second SMA connector is
upside-down, compared to the first. Add a little solder to make a good connection.
b Solder the center conductor of the second SMA connector to the center conductor of the first
SMA connector and the leads on the left side of the pin strip.
c Rotate the assembly 180 degrees and solder the two SMA board mount connector frames
together.
Check your work:
a Ensure that the following four points have continuity between them: The two pins on the left
side of the pin strip, and the center conductors of each SMA connector.
b Ensure that there is continuity between each of the two pins on the right side of the pin strip,
and the SMA connector frames.
c Ensure that there is NO continuity between the SMA connector center conductor and the SMA
connector frame (ground).
Finish creating the test connectors:
a Attach an SMA m-m adapter to one end of each of the four SMA/Flying Lead test connectors.
b Attach a 50 ohm terminator to the other end of the four SMA/Flying Lead test connectors.
