介绍了在ROF系统中毫米波产生的三种基本原理，对于初学者打基础来说相当不错。-Introduced in the millimeter wave ROF system produced three basic principles, laying the foundation for the beginner is quite good.

A simple multi-band QPSK signal transmission scheme, constructed by using an optical remote up-conversion technique and a Schottky diode RF detector, is theoretically analyzed and experimentally implemented in a 60-GHz millimeter wave (mm-wave) r
