[0001] A phased array antenna includes a plurality of antenna elements configured to operate in a transmit mode and a receive mode, and a plurality of FEMs configured to operate corresponding antenna elements to transmit and receive RF signals. The phased array includes a DBF configured to translate between the RF signals and corresponding digital signals, the DBF coupled to the FEMs over at least one RF distribution network. A phased array includes a modem coupled with the DBF and configured to supply the corresponding digital signals for the transmit mode, process the corresponding digital signals for the receive mode, initiate a calibration, in the transmit mode and in the receive mode, of the FEMs based on an aggregate power consumption of the FEMs, and write compensation values for the FEMs, for the transmit mode and the receive mode, to a nonvolatile memory, the compensation values computed based on the calibration.
