    Figure 1: PA10W RF power amplifier module RF Input and Output Connectors A top view of the PA10W module depicting RF input and output connectors is shown on the next page in Figure 2. When connecting the PA10W power amplifier, the RF signal source should be connected to the SMA jack on the right hand side (top view) of the circuit (RF in).
