本文在65nm CMOS工艺中实现了一个60GHz频段2×2相控阵发射机，能够独立调谐垂直和水平极化，以增加有效各向同性辐射功率并补偿60GHz频段的高路径损耗。
independent tuning of both vertical and horizontal polarizations realized in 65nm bulk CMOS is described in this paper. Phased-array transmitters increase the isotropic radiated power of a stand-alone transmitter over a single radiating element by 20*log10N dB, where N is the number of elements in the array [1,2]. They are well-suited to mm-Wave applications where spatial selectivity of the phasedarray antenna compensates for beam directionality, and greater antenna gain helps offset path loss (88dB at 10m) that constrains 60GHz-band Tx/Rx link spans. Implementation in bulk CMOS technology favors co-integration of RF and baseband circuitry and the potential low production cost in volume for applications such as short-range Gb/s communication at (56 to 64GHz), collision avoidance radar (77/79GHz), and radio imaging (94GHz band).
