摘要

Due to its wide bandwidth, less interference and higher directivity, millimeter-wave wireless communication has been attracting the interest of many applications such as radars, sensors and wireless local area networks. Especially, the release of the license-free band around 60-GHz has given rise to research and development efforts on millimeter wave circuits and applications. There are four 2.16-GHz wide channels available in the 60 GHz spectrum which supports multi-Gigabit data rate on each channel.;Recently, 60-GHz millimeter-wave wireless data center networks (DCN) have been introduced to alleviate issues of wire cluttering and inflexibility in existing data center interconnects. For efficient design of wireless DCNs, highly flexible and accurate point-to-point links are required, which can be accomplished by using high performance phased-array transceivers. In this dissertation, a hybrid-mode phased-array receiver is proposed, which incorporates continuous and quadrature phase shifters, resulting in reducing the design difficulty to achieve minimum phase resolution less than 5 degree. A newly invented continuous phase shifter is also introduced in this dissertation. The frequency response of the continuous phase shifter is the same at the all-pass network, thus having the nearly constant input/output return loss and insertion loss regardless the insertion phase condition. 7 dB of insertion loss and > 90 degree phase rotation capability are obtained from measurement.;A phased-array receiver is designed and fabricated in IBM130nm complementary metal- oxide-semiconductor (CMOS), which is comprised of a low noise amplifier, mixer, continuous phase shifter and quadrature phase shifter. From the measurement, 16 dB of the RF return loss and gain are respectively achieved in the bandwidth from 53-GHz to 57-GHz. The obtained noise figure and input P1dB are < 14 dB and < -25 dB, respectively.
