Abstract: This paper presents the first co-designed 64-channel broadband PMUT array and multi-level CMOS transmitter (TxCMOS) in 0.18μm BCD platform, achieving a record 70% bandwidth at 5MHz with only ...

Abstract: In this article, the beam scanning range expansion and polarization diversity of a circularly polarized (CP) tightly coupled (TC) phased array are investigated. A systematic theoretical ...
