Power Amplifier Enable pin. A digital control signal with logic high (power up) and logic
low (power down) is used to turn the device on and off.
Power amplifier RF input, external input matching network with DC blocking is required
Bias supply voltage
Stage 1 collector supply voltage, external inter-stage matching network is required
PA Output and Stage2 collector supply voltage, external output matching network with
DC blocking is required
Heatslug Die Pad is ground
CC
varies the PA output power between minimum and maximum values
