HARDWARE INTERFACE
•
The RF Input connector is SMA (female).
•
The RF Output connector is SMA (female).
•
The pin-out definitions for the Micro-D Hybrid, 7 +2-pin socket connector are provided in Table
5. In a typical installation, the PA module is mated to a host controller board via a cable harness.
The RF Out SMA connector is the antenna connection. This connection should
always be loaded into 50
Ω, otherwise the PA could be damaged.
