Abstract:This paper reports the first large-scale, dense sub-THz heterodyne array featuring: (1) compactness of units: two interleaved 4×4 arrays with A/2 unit pitch are integrated in a 1.2-mm2 space; (2) multi-functionality of circuits: each array unit simultaneously achieves LO generation, inter-unit synchronization, incident wave coupling and down-conversion; (3) global phase locking: a strongly-coupled 2D LO network is phase locked to a 75-MHz reference, enabling phase-coherent pairing with off-chip transmitters; (4) scalability: array scale increase and lower LO phase noise are facilitated by elim
