Abstract
A system and a method for calibrating an antenna using trim bits and non-volatile memory is disclosed. In one aspect, an apparatus includes a power amplifier configured to at least amplify the output signal of the first antenna. The power amplifier includes multiple stages. The apparatus further includes a trim control circuit configured to adjust a bias of one of the stages of the power amplifier, using trim bits from non-volatile memory. The trim control circuit is further configured to scale the bias of one of the plurality of stages of the power amplifier by an integer between 0 and 2n−1 corresponding to a binary number formed by the first plurality of trim bits, wherein n corresponds to the number of trim bits.
