Description

The HR2731-50A is designed for Radar system application frequencies from 2.7 ~ 3.1GHz and GaN HEMT technology has been used that performs high breakdown voltage, wide bandwidth and high eff iciency. HR2731-50A has been designed 2 stages to have higher Gain at the wide frequency range of 2.7 ~3. 1GHz. 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.

  • - 7 Vds2 - - 14 GND Recommended Pattern Recommended Pattern Detail ‘A’ * 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 PC B 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 o uter layers near the part to ensure optimal thermal performance. Detail Pattern ‘A’

The Gallium Nitride Transistor requires a Negative V oltage Bias which operates alongside a Positive V oltage 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. Turn On Turn Off - Sequence Timing Diagram -
