Abstract
A control interface circuitry configured to control an array element of a phased array antenna system. The control interface circuitry comprises: 1) a first RF combiner network for transceiving first RF signals with first transmit/receive path circuitry in the array element; and 2) a central controller configured to communicate with control logic circuitry in the array element, the control logic circuitry controlling operation of the first transmit/receive path circuitry. During Data mode, the central controller transfers control data to the control logic circuitry via the first RF combiner network. During RF mode, the first RF combiner network transceives the first RF signals with the first transmit/receive path circuitry. The control interface circuitry further comprises: iii) a second RF combiner network for receiving second RF signals from second receive path circuitry in the array element. During Data mode, the central controller transfers a clock signal to the control logic circuitry via the second RF combiner network. During RF mode, the second RF combiner network receives the second RF signals from the second receive path circuitry.
