We are investigating using the LMG1210 GaNFET gate driver for a high-frequency half-bridge power stage, and have reviewed two designs we found on the TI site (LMG1210EVM and TI Designs: TIDA-01634).
However, Figure 10.2 of the spec sheet for the LMG1210 driver has a detail of an example layout that does not seem to be from either of the above designs. The figure shows a section of an interesting-looking board, but is incomplete and has very little explanation.
I am writing to ask if any more information about the layout in the figure is available? In particular, can you provide the full layout? also a BOM? Interestingly, the figure shows a peculiar foil pattern that looks like a millimeter wave low-pass filter - any explanation of that would be great as well.
Thanks
