几年前,在文献[1]中表明:局部充满铁氧体的环行器的频率特性,与切比雪夫型相近。但是还没有这种环行器的理论,故需要利用文献[1]中提出的模式加以证明。最近,文献[2]中报导了具有切比雪夫频率特性的丫环行器的构成。本文旨在深入研究工程制作具有最崖性能的铁氧体隔离器的方法。我们选定了铁氧体隔离器的等效电路,这种隔离器由H面环行器组成,其一端接入负载[3](图1)。隔离器在中心频率是一个理想的环行器,在其他的频率下,环行不理想;反方向的 Several years ago, it was shown in [1] that the frequency characteristic of a partially filled ferrite circulator was similar to the Chebyshev type. However, there is no such theory of circulator, so it needs to be proved by the model proposed in [1]. Recently, the composition of the Ya circulator with Chebyshev frequency characteristics has been reported in [2]. The purpose of this paper is to study in depth the method of making a ferrite isolator with the most extreme performance. We selected the equivalent circuit of the ferrite isolator, which consists of an H-plane circulator with one end connected to the load [3] (Figure 1). Isolator at the center frequency is an ideal circulator, at other frequencies, the ring is not ideal; the opposite direction
