connectors are shown in Figure 7.
• CDMA RF input — connects to duplexor
• CDMA RF output — connects to antenna pad through vias
• GPS RF input — connects to GPS ceramic filter output
• GPS RF output — connects to GPS antenna-matching circuits
• RF connector — connects to coaxial cable
If the RF input is not connected properly to the RF output, then the RF connector must
be replaced.
