Function
VCC2
Description
Power supply for the driver stage and interstage matching. This pin
forms the shunt inductance needed for proper tuning of the interstage
match. Please refer to the application schematic for proper configura-
tion, and note that position and value of the components are important.

Ground connection for the output stage. This pad should be connected
to the groundplane by vias directly under the device. A short path is
required to obtain optimum performance, as well as to provide a good
thermal path to the PCB for maximum heat dissipation.
