六端口技术是七十年代出现的一种新技术,它为测量微波网络的参量提供了新的途径。基于六端口测量技术的基本原理制成的自动网络分析仪,配合计算机和接口电路,能自动测量微波部件的反射系数和传输参量,因而在自动化技术的发展中,这种新技术的出现引人注目。六端口测量技术的特点是以测量功率(或电压幅值)的方法替代相位测量,因此,测量系统中无需具有对相位敏感的元件,从而使测 Six-port technology is a new technology emerged in the seventies, which provides a new way to measure the parameters of microwave networks. Automatic network analyzer based on the principle of six-port measurement technology, with the computer and interface circuit, can automatically measure the reflection coefficient and transmission parameters of the microwave components, so in the development of automation technology, the emergence of this new technology Attention. The feature of six-port measurement technology is the measurement of power (or voltage amplitude) instead of the phase measurement method, the measurement system does not need to have a phase-sensitive components, so that measurement
