Reconfigurable X-Band 4×4 Butler array in 32nm CMOS SOI for angle-reject arrays

Abstract

Introducing reconfigurable spatial filtering prior to ADC in digital beamforming (DBF) receiver (RX) arrays can improve the RX tolerance for in-band out-of-beam jammers. Such spatial filtering can be achieved using a Butler matrix that provides multibeam outputs. In this paper, an integrated 4×4 reconfigurable X-Band Butler matrix is designed in SOI… (More)
