Convert RFX2400 to RFX1200

What is involved in changing an RFX2400 to an RFX1200?

I was figuring I would just look at the BOM differences, but
there seems to be no BOM for the RFX1200.

Then I figured I give comparing the images on the ETTUS site,
but the RFX1200 image link just shows you the RFX2400.

Thank you,

To convert to an RFX1200, you need to:

  • Cut the traces which FIL1

  • Put a capacitor in C204, anything between about 50pF and 1000pF is
    fine, size 0603

  • Put the board on side A of a USRP, power it up, and reburn the EEPROM
    using the command
    usrp/host/apps/burn-db-eeprom -A -f -t rfx1200_mimo_b

  • When we do it here, we also change some of the final amp tuning
    components if the power out is a little low. This is not always
    necessary, but sometimes gets another dB of extra power.
