【摘要】：提出了一種利用線性變換綜合星型結(jié)多工器的方法。該方法基于線性變換綜合出多工器的每個信道濾波器S參數(shù)對應(yīng)的特征多項式,利用文獻中已有的技術(shù)綜合出多工器的N階耦合矩陣。給出了多工器N階耦合矩陣的構(gòu)造方法,并推導(dǎo)了多工器S參數(shù)和群時延與N階耦合矩陣的關(guān)系。為了驗證該方法,給出了一個五工器及一個雙工器的綜合實例,其中雙工器被進一步設(shè)計、加工與測試,測試結(jié)果與綜合結(jié)果相吻合,進一步驗證了該方法的準(zhǔn)確性。
[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.
