Description
RF input. Input is matched to 50 and DC block is provided internally.
Bias current control voltage for the first and second amplifier stage.
Power detector which provides an output voltage proportional to the RF output power level. May need external
decoupling capacitor for stability. May need external circuitry to bring output voltage to desired level.
Ground.
RF Output.
Voltage supply for the second amplifier stage.
Voltage supply for the first amplifier stage.
Supply voltage for the bias reference and control circuit. May be connected with V_C1 and V_C2 (with a single sup-
ply voltage) as long as V_CC does not exceed +4.5V_DC in this configuration.
The center metal base of the QFN package provides DC and RF ground as well as heat sink for the amplifier.
