摘要

毫米波无线电正日益成为传统双绞线、电缆和光纤技术的竞争替代品。新的频谱频带正在被分配,以允许类似蜂窝的本地通信网络的商业发展。由于固态器件在毫米波频率下的输出功率较低,因此必须将许多器件的输出组合起来,以产生链路预算分析所规定的功率水平。通过将大量带天线的器件集成成阵列,可以使辐射信号在自由空间中高效地相干组合。本文将讨论为这些新的无线频段开发高功率准光发射机的正在进行的活动。

High power quasi-optical sources for millimeter-wave base-station applications
Millimeter-wave radios are becoming an increasingly competitive alternative to traditional twisted-pair, cable, and fiber technologies. New spectrum bands are being allocated to allow for the commercial development of local, cellular-like communication networks. Because solid-state devices have low output powers at millimeter-wave frequencies, the outputs from many devices must be combined to produce the power levels dictated by link-budget analysis. By integrating a large number of devices with antennas into an array, radiated signals can coherently combine in free-space with high efficiency. This paper will discuss on-going activities to develop high-power quasi-optical transmitters for these new wireless bands.
