Amplifier Output Pin. A choke inductor is best RF performance, all ground pins should be connected necessary to provide power from the 5V supply and to to the printed circuit board ground plane. The exposed pad provide RF isolation. For best performance select a choke should have multiple via holes to an underlying ground with low loss and high self-resonant frequency (SRF).
