An AESA may include a point-to-point serial interface between RFIC that implements positional addressing and is extensible to an unlimited amount of RFIC. A controller of the AESA may access registers of one or more RFIC and sends control and synchronization signals using a low-latency serial interface. The AESA may include primary and secondary interfaces which form a mesh network allowing communications around defective devices or interconnects and reduced area overhead resulting in array size reduction. The AESA may include health monitoring to determine location of data network faults providing improved array mean-time between failure (MTBF) and fault recovery. The AESA may allow faster antenna array configuration and beam steering rates for improved uptime and optimized scan modes. The AESA may experience improvements in manufacturability and reliability due to redundancy and fault isolation. The AESA may include more RFIC per serial interface allows scaling into larger arrays.
