Name
Description
RF IN
RF input for the power amplifier. This pin is DC-shorted to GND but AC-coupled to the transistor base of the first
stage.
VCC
Supply voltage for the bias reference and control circuits.
VB1
Bias current control voltage for the first stage.
VB2
Bias current control voltage for the second stage.
VB3
Bias current control voltage for the third stage.
RF OUT
RF output for the power amplifier. This pin is AC-coupled and does not require a DC-blocking capacitor.
VC1
Power supply for the first stage amplifier.
VC2
Power supply for the second stage amplifier.
VC3
Power supply for the third stage amplifier.
GND
The center metal base of the MLP package provides both DC and RF ground as well as heat sink for the power
amplifier.
These are unused pins and not connected to the device. They can be treated either as open pins or connected
to ground for better heat dissipation.
