Abstract
Systems and methods described herein are directed towards an active electronically scanned array (AESA) that can perform both frequency division duplexing (FDD) operations and time division duplexing (TDD) operations. The AESA includes a switch network having one or more switching stages coupled between a transceiver and one or more array elements to switch the AESA between FDD operation and TDD operations, modify a function of one or more of the array elements in the AESA and/or swap portions of the AESA between different functions. The switch network can be disposed in a feed portion of the AESA. Thus, functions of each of the array elements or subarrays of multiple array elements in the AESA can be modified at a feed portion of the AESA. The array elements can be configured for TDD operations and FDD operations and can be configured as a transmit elements, receive elements or isolation elements.
