A near field communications (NFC) device is disclosed that is capable of optimizing a gain for received signals. Measurements are made of signals received from an NFC environment and are compared to one or more threshold hold values. Based on the comparison, it is determined whether the measurements indicate underamplification or overamplification. Depending on the results of the analysis, one or more components within the NFC device is adjusted to increase or decrease the gain, respectively. The measurements may be taken during an unloaded baseline state or during loading, and may be compared to previous measurements to estimate their accuracy.
