【摘要】：提出了一种利用线性变换综合星型结多工器的方法。该方法基于线性变换综合出多工器的每个信道滤波器S参数对应的特征多项式,利用文献中已有的技术综合出多工器的N阶耦合矩阵。给出了多工器N阶耦合矩阵的构造方法,并推导了多工器S参数和群时延与N阶耦合矩阵的关系。为了验证该方法,给出了一个五工器及一个双工器的综合实例,其中双工器被进一步设计、加工与测试,测试结果与综合结果相吻合,进一步验证了该方法的准确性。
[Abstract]:A method of synthesizing star junction multiplexer by linear transformation is presented. Based on the linear transformation, the characteristic polynomials corresponding to the S parameters of each channel filter of the multiplexer are synthesized, and the N-order coupling matrix of the multiplexer is synthesized by using the existing techniques in the literature. The method of constructing N-order coupling matrix of multiplexer is given, and the relation between S-parameter and group delay of multiplexer and N-order coupling matrix is deduced. In order to verify the method, a synthesis example of a quad and a duplex is given, in which the duplex is further designed, processed and tested, and the test results are in agreement with the synthesized results, and the accuracy of the method is further verified.
