Analog Self-Interference Cancellation Networks for STAR Phased Arrays

Abstract

Theoretical performance of ideal multi-channel analog Self-Interference Cancellation (SIC) networks are considered for Simultaneous Transmit and Receive (STAR) phased array applications. Three different matching criteria are described for designing analog SIC networks, two of which may be implemented using a single cancellation path per element. Simulated results are presented comparing the performance of each SIC type under finite dynamic range limitations.
