Hi Daisuke,
The LMG352xR030 series of devices have the same switching performance. You can use the following half-bridge daughter card and the motherboard for the double pulse test.
Half-bridge daughter card EVM:

Hi Bagadi,
The bias supply for a daughter card half-bridge unit (LMG342XEVM) on motherboard (LMG342x-BB-EVM) draws < ~150mA. So based on that 3A output at 12V supply should be enough to meet the power requirement.
Thanks,
Subhransu
Part Number: LMG3422EVM-043 Other Parts Discussed in Thread: LMG342X-BB-EVM I would like to know the part number of the power pins and the signal pins, in their male (LMG3422EVM-O43) and female (LMG342X-BB-EVM) versions. Thanks in advance
Part Number: LMG34XX-BB-EVM Other Parts Discussed in Thread: LMG3410EVM-018 Hello,
I am using LMG34XX-BB-EVM with LMG3410EVM-018. DC input 300V, 12V isolated dc input and no load at the output(just a multimeter). I am using LaunchXL28379D for PWM input…
John, in the user guide for LMG342X-BB-EVM, what is the switching frequency at the described 4KW operation?
I found this document from TI, this is the thermal evaluation of the same GAN fets at 4KW.

As it is shown here with 1Ghz lecroy oscilloscope we can't get the 102V/ns rise time as it should support according to the datasheet. We have checked R5. It is much more longer. What is the problem here?

You may refer to an external dead-time generating circuit that we've used for the EVM of a different device - https://www.ti.com/tool/LMG342X-BB-EVM#design-files . In the user guide for this EVM, you can find the dead-time generating circuit below:
