HARDWARE INTERFACE  

 

The transceiver interface connector, “XCVR,” is SMA (female). 

 

The antenna connector, “ANT,” is SMA (female). 

 

The pin-out definitions for the 15 pin Micro-D socket connector, “CTRL/PWR,” are provided in 

Table 4. In a typical installation, the amplifier module is mated to a host controller board via a 

cable harness. 

 

 

The ANT SMA connector is the antenna connection. This connection should always 

be loaded into 50 

Ω

, otherwise the amplifier could be damaged.
