Description
The HR2933-70A is designed for Radar system application frequencies from 2.9 ~ 3.3GHz and GaN HEMT technology has been used
that performs high breakdown voltage, wide bandwidth and high efficiency. HR2933-70A has been designed 2 stages to have higher
Gain at the wide frequency range of 2.9 ~3.3GHz. GaN HEMT technology has been used to every amplifier in it for better reliability.
Since it is high efficiency amplifier, it can perform at max 10% duty cycle and 500us of pulse width. A droop feature is below 1dB for
long pulse usages.

Caution
The drain voltage must be supplied to the device after the gate voltage is supplied
Turn on Turn on the Gate Voltage supply and last turn On the Drain voltage supplies
Turn off Turn off the Drain Voltage and last turn off the Gate voltage
Note
Test Pulse conditions = 100us, 10%
Above electrical specifications is measured by connecting electrolytic condenser 200uF to DC. Please make sure that electrolytic
condenser is connected properly while testing the module.

* Mounting Configuration Notes
1. For the proper performance of the device, Ground / Thermal via holes must be designed to remove heat.
2. To properly use heatsink, ensure the ground/thermal via hole region to contact the heatsink. We recommend the mounting screws
be added near the heatsink to mount the board
3. In designing the necessary RF trace, width will depend upon the PCB material and construction.
4. Use 1 oz. Copper minimum thickness for the heatsink.
5. Do not put solder mask on the backside of the PCB in the region where the board contacts the heatsink
6. We recommend adding as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance.

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.
