英文摘要：

The fast development of microelectronics makes the cutoff frequency of semiconductor devices exceed terahertz,which significantly improves the frequency of terahertz circuits. The solid-state electronic circuits entrance terahertz frequency. Solid State Terahertz Devices and Circuits are believed to be one of the most important promising technologies in space applications. The development of InP-based three-terminal terahertz solid state electronic devices and schottky barrier diodes, as well as the related circuits are reviewed. And it is pointed that terahertz monolithic integrated circuits （TMIC） is the most possible solution for the future development of this technology.
