近１０多年，毫米波频段（３０～３００ＧＨｚ）的开发利用，无论是基础理论还是应用技术，都取得了重大进展。作为毫米波领域重要组成部分的测量仪器和设备，以及某些关键元器件，相应地亦取得了重大进展。传统微波段的仪器及元器件的频率，几乎已全部扩展到１４０～１７０ＧＨｚ，并在不断地向更高频率扩展。本文将对国外毫米波测量仪器的现状和发展进行简要介绍。 In the past 10 years, great progress has been made in the development and utilization of the millimeter-wave band (30 to 300 GHz), both in basic theory and in applied technologies. As an important part of the millimeter-wave measurement instruments and equipment, as well as some key components, correspondingly, significant progress has also been made. Traditional microwave devices and components of the frequency, almost all extended to 140 ~ 170GHz, and continue to expand to higher frequencies. This article will introduce the status and development of foreign millimeter wave measuring instruments.
