Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays do not ...

A fully-integrated 16-element 60-GHz phased-array receiver is implemented in IBM 0.12-μm SiGe BiCMOS technology. The receiver employs RF-path phase-shifting and is designed for multi-Gb/s non-line of ...
