Abstract:

The Aperture-Level Simultaneous Transmit and Receive ALSTAR architecture enables extremely high isolation between adjacent transmitting and receiving sub-arrays in a digital phased array without analog cancellers or other complex front-end hardware. An 8-channel ALSTAR array prototype was constructed and demonstrated to achieve 125.5 dB effective isotropic isolation between broadside transmit and receive beams over a 100 MHz instantaneous band centered at 2.45 GHz.
