Abstract :
Using a broadband equivalent circuit of a lossy, nonideal circulator, single-stage and multistage negative-resistance amplifier circuits are studied to determine the effect of circulators and isolators on performance. It is found that feedback phenomena controlled by circuit phase shifts play an important part in determining the amplifier response.
