DESCRIPTION
Bias Control. The overall current is set by the current sourced through the bias pin. See the Bias Circuitry
section.
Second-Stage DC Supply Voltage. Sets the bias and external matching for the second amplifier stage.
Requires a small inductance. Bypass to ground using the configuration in the Typical Operating Circuit.
Second-Stage Ground. See the Applications Information section for detailed layout information.
First-Stage DC Supply Voltage. Sets the bias and external matching for the first amplifier stage. Requires a
small inductance. Bypass to ground using the configuration in the Typical Operating Circuit .
Third-Stage Ground. See the Applications Information section for detailed layout information.
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 50 Ω . Requires an external DC-blocking cap.
