摘　　要：With the development of multi-band wireless communication and the increasing data transmission rate,the circulator as an antenna interface must be able to work in multiple frequency bands and provides large bandwidth.It presents a high challenge to the design of circulators,especially the active quasi-circulators.In this survey,we review the representative active quasi-circulators and summarize three different techniques and the corresponding structures to show an incremental improvement of the isolation and bandwidth of the active quasi-circulators.In addition,we also compare the performance of several state-of-art active circulators,and analyze their advantages and disadvantages.Finally,we conclude the future trend of the active quasi-circulators. 关键词：active quasi-circulator MULTIBAND bandwidth isolation LINEARITY insertion loss
