Feedthrough plate
Purpose of
feedthrough
plate
The feedthrough plate converts the normal SMA connector from the CTU to an
N-type connector. Each feedthrough plate has a pair of these converters, one
for each of two CTUs. The top N-type connectors are used to connect with
either a CCB, or at the (optional) third Tx port on the top of a DDF Tx block.
The plate is attached to the base of the top panel basket using six M4 screws.
