    CYBLE-012011 Antenna detune by epoxy potting

    HeGi_2497906

      Hello, we are nearing the end of a development effort and have resolved a ~50% reduction in RF range directly to the Epoxy Potting we are required to encapsulate our product with, due to the environment.

       

      Here is the key question, can we use the digital capacitor array to adjust for the epoxy, in other words, is if feasible to use the digital cap trim to correct for the added capacitance of the epoxy.

       

      This is the line CY_SET_XTND_REG32((void CYFAR *)(CYREG_BLE_BLERD_BB_XO_CAPTRIM), 0xBCBC); can you help me better understand the mechanism, and how to potentially "tweak" these values to recover our range?
