The spacers are installed with the SX-550-1701 WLAN model as shown below:
Figure 23
The spacers are installed with the SX-550-0700 Ethernet model as shown below:
Do not over-tighten the screws during the installation procedure. Although the spacers provide protection
against flexing, they can compress or break if too much torque is applied.
Antenna Connectors
The SX-550 Module has two SMT Ultra-miniature coaxial connectors (U.FL). Table 14 describes the
connector types.
For single antenna use, connect to the primary antenna connector, as shown in Figure 25.
For diversity antenna use, connect to both the primary and auxiliary connectors.
Part Number 40183-101
IMPORTANT: In order to prevent flexing of the SX-550 boards during the installation process, you must use spacers.
Silex provides spacers on the SX-550-1701 and SX-550-2701 WLAN models that go between the base module board
and the radio module board. However, because of the wide range of possible OEM daughtercard connectors and other
design issues, you must provide the three spacers that go between the SX-550 base module board and your
daughtercard.
IMPORTANT: Silex does not recommend soldering the SX-550 directly to your device’s daughteroard. Soldering the SX-
550 will violate the standard warranty. If you must solder the SX-550, please contact Silex Technical Support at 866-765-
8761 (U.S. toll-free) or [phone], or e-mail us at

Using
IMPORTANT: If you are planning to use the FCC Modular Approval for the SX-550-2701, please refer to Appendix D
for installation requirements. YOU MUST LABEL YOUR PRODUCT WITH THE SX-550-2701 FCC ID AND/OR IC ID,
AND YOU MUST USE THE SILEX 108-00016-050 ANTENNA AND 131-20110-050 CABLE OR AN ANTENNA AND
CABLE WITH EQUIVALENT SPECIFICATIONS.
IMPORTANT: If you are only using a single antenna, you MUST connect this antenna to the Primary Antenna
Connector.
