Pin Function Description

Interface Schematic

VCC2

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.
