Overview

The SMA2RJ45EVK is an SMA connector to RJ45 connector adapter boards developed to
complement National Semiconductor’s evaluation boards for which evaluation with CAT5e cable
assemblies may be desirable (e.g. DriveCable02EVK, LVDS-18B-EVK, DS25BR100EVK, etc.).

Board Description

Figure 2 shows the adapter board drawing with the silkscreen annotations. The 1.75 by 1.0 inch,
four-layer PCB is designed to bring RJ45 connector signal pins to SMA connectors. There is only
one SMA pair installed (J2 and J3) on the board. J2 connects to the pin 4 pf the RJ45 connector
(J1); J3 connects to the pin 5 of J1. The end user may access the remaining RJ45 pins using the
copper pads located on the bottom of the board.
