use the Hirose U.FL
connector removal tool
(P/N UFL-LP-N-2(01)) to
prevent damage to the
module or coaxial cable
assembly.
• Use a Hirose U.FL connector (model U.FL #CL331-0471-0-10) to attach an
antenna to a connection point on the module, as shown in Figure 3-1 (main
RF connector or diversity RF/GPS connector).
• Match coaxial connections between the module and the antenna to 50 
• Minimize RF cable losses to the antenna; the recommended maximum cable
loss for antenna cabling is 0.5 dB.
