Description
No connection required. These pins may be connected to
RF/DC ground without affecting performance.
This pin is AC coupled
and matched to 50 Ohms.
Power control pin. For maximum power, this pin should

be connected to 5V thru a 56 Ω resistor. A high-voltage or
small resistor is not recommended for lower idle current.
This voltage can be reduced or the resistor increased.
