Abstract

Digital RF technology has been developed and has been applied to below 6 GHz wireless applications. By replacing the IC die consumptive RF/analog circuit blocks by digital signal processor and circuit, digital rich/small transceivers can be realized. Since the foundation of this technology is based on the Nyquist theory, the operational frequency of the circuit has been limited by the Nyquist frequency (=1/2 of sampling clock frequency). As a result, the maximum operational RF frequency of existing digital RF technology was below 6 GHz. In this paper, a new direct digital RF technology that utilizes the higher-order Nyquist zones is introduced. This technology enables handling RF signal in beyond Nyquist frequency range which means over 6 GHz range. The results of fabricated 26/28 GHz-band transmitter/receiver are reviewed. Since the transceiver architecture with the proposed technologies does not require an RF local oscillator and up/down converters, it is suitable for microwave/millimeter-wave multi-antenna systems such as next generation satellite on-board digital beam forming and Beyond 5G fully digital Massive multiple-input multiple-output systems.

毫米波 DBF 系统的直接数字 RF 收发器技术

数字射频技术已被开发并应用于 6 GHz 以下的无线应用。通过用数字信号处理器和电路取代消耗集成电路芯片的射频/模拟电路块，可以实现富数字/小型收发器。由于这项技术的基础是奈奎斯特理论，因此电路的工作频率受到奈奎斯特频率（=采样时钟频率的 1/2）的限制。因此，现有数字射频技术的最高工作射频频率低于 6 GHz。本文介绍了一种利用高阶奈奎斯特区的新型直接数字 RF 技术。该技术可处理奈奎斯特频率范围以外的射频信号，即 6 GHz 以上的射频信号。本文回顾了 26/28 GHz 波段发射器/接收器的制造结果。由于采用所提技术的收发器架构不需要射频本地振荡器和上/下转换器，因此适用于微波/毫米波多天线系统，如下一代卫星机载数字波束成形和 Beyond 5G 全数字大规模多输入多输出系统。
