Abstract: An integrated circuit for use in a phased array antenna system having a central processing unit. The integrated circuit is associated with one of a plurality of antenna elements of the phased array antenna system. The integrated circuit includes an ID memory for storing a unique ID addressable by the central processing unit, and receives global commands from the central processing unit globally transmitted over a distributed serial bus. Upon detecting a global command, the integrated circuit compares an ID address associated with the global commands with the ID stored in the ID memory. The integrated circuit recognizes global commands as local commands to be executed locally when the ID address associated with the global commands is the same as the ID stored in the ID memory. In response to the local commands, the integrated circuit generates and provides control signals to the associated one of the antenna elements of the phased array antenna system.
