Abstract

This study deals with a passive RF duplexer integrated with a two-notch band. To design the model, a band-pass filter is considered. Using micro-strip technology, the RF duplexer substation is simulated. It is a rectangular in parallel coupling with frequency bands of 1 and 5 GHz while existing three ports. Moreover, to enhance the impedance coefficient and decrease the admittance, the method of complementary paired resonators is taken into account. Furthermore, scattering parameters were used by the step impedance method to make an integrated monolayer substrate from signal branching in duplex mode. Thus, the band-pass filter making the frequency cut-off bands allows designing GSM-4G radars. The low cut-off microwave band is included in these bands at the 77 MHz central frequency and the second cut-off band for GSM-4G radars at the 437 MHz central frequency. The duplexer has the total dimensions of 14 mm × 99 mm and the presented RF duplexer is simulated in CST.

利用带通滤波器提高混合射频双工器的信号隔离度
本研究涉及一个集成了双缺口带的无源射频双工器。在设计模型时,考虑了带通滤波器。使用微带技术模拟了射频双工器分站。它是一个矩形并联耦合器,频带为 1 和 5 GHz,同时存在三个端口。此外,为了提高阻抗系数和降低导纳,还考虑了互补成对谐振器的方法。此外,通过阶跃阻抗法使用散射参数,在双工模式下从信号分支中制作集成单层衬底。因此,设计 GSM-4G 雷达时,可以使用带通滤波器制作频率截止带。在这些频段中,低截止微波频段的中心频率为 77 MHz,GSM-4G 雷达的第二个截止频率为 437 MHz。双工器的总尺寸为 14 毫米 × 99 毫米,并在 CST 中对所介绍的射频双工器进行了仿真。
