Preliminary
GaN Hybrid Power Amplifier HR2933-70A
Precautions
This product is a Gallium Nitride Transistor.
The Gallium Nitride Transistor requires a Negative Voltage Bias which operates alongside a Positive Voltage Bias. These Biases are
applied in accordance to the Sequence during Turn-On and Turn-Off.
The Pallet Amplifier does not have a built-in Bias Sequence Circuit. Therefore, users need to either apply positive voltages and
negative voltages in the required sequence, or add an external Bias Circuit to this Amplifier.
The required sequence for power supply is as follows.
During Turn-On
1. Connect GND.
2. Apply Vgs1 and Vgs2.
3. Apply Vds1 and Vds2.
4. Apply the RF Power.
During Turn-Off
1. Turn off RF power.
2. Turn off Vds1,2 and then, turn off the Vgs1 and Vgs2.
3. Remove all connections.
