... RF2402 Pin Function Description 10 GND1 Ground connection of the LO phase shift network. This pin should be connected directly to the ground plane. 11 GND Ground connection for other circuits. Keep traces short and connect to ground plane immediately. 12 GND Same as pin 11. 13 GND2 Ground connection for the RF output stage. A good ground connection is especially important at this pin to avoid interference with other cir- cuits ...
