Simultaneous Multi-Band, Multi-Beam, and Multi-Function TX/RX Phased Array Systems

This paper presents new TX and RX phased array systems that provide simultaneous multi-band, multi-beam, and multi-function operation over the millimeter wave region of the electromagnetic spectrum. The overall system uses separate TX and RX arrays that are based on optical up- and down-conversion as the means to implement beam forming with near-unlimited beam-bandwidth products. It does so in a non-blocking and multi-tasking manner, which enables numerous commercial and DoD applications.
