Power-Detector Output. This output is a DC voltage indicating the PA output power.
First-Stage and Bias-Control Circuit Ground
RF Output. Open-collector output. Requires a pullup inductor, which is part of the matching network.
Shutdown Input. Drive logic low to place the device in shutdown mode. Drive logic high for normal
operation.
Bias Circuit DC Supply Voltage. Bypass to ground using the configuration in the Typical Operating Circuit.
RF Input. Internally matched to 50Ω. Requires an external DC-blocking cap.
