Highest measured bandwidth was ~250MHz on a the FE Rev.1 front end module. The simulations show a BW of 400 MHz, so it should be possible to get to 350 MHz with some finagling.

Front end has been changed to use the BUF802 chip, preliminary testing indicates a very similar bandwidth to the original front end of about 250 MHz. I suspect the inline terminator used for the tests may be the cause of this.

New 50 ohm path has a BW of 900MHz, high-z paths should be good to 500MHz
