| Popis: | 107 This paper proposes a complete diplexing power dividers design flow, starting with the filter design, and then using the odd-even mode analysis to derive the filtering power divider architecture, and the design of the isolation resistor, and use the open stub type and SIR type impedance converter goes to equivalent K inverters. Frequency of the transmission zero can be designed by the length of the open stub. Therefore, we can enhance the suppression ability outside the passband, and can maintain the characteristics of the passband of the filtering power divider, enhance the passband selectivity by using the characteristics of the transmission zero point, and then design diplexing power dividers with good passband selectivity. And have good isolation between the passbands. The diplexing power dividers can be used for two frequency bands, and the two frequency bands have the function of filtering the power divider at the same time. In the past, such a function was required to be realized by using a diplexer and two power dividers. The architecture can be combined into a whole circuit, which saves the circuit area and saves the number of components required. It is well verified in both simulation and implementation. The return loss of the measurement results is greater than 17dB, which is quite consistent with the simulation results. Through this design process, it can meet the requirements of different circuit specifications and realize on various PCB circuits, which has the advantages of low cost, easy design, and easy implementation. |
