Abstract
The rectangular dual-mode resonant cavity has the characteristics of high Q value, steep drop from pass band to stop band, and very low insertion loss. However, since the resonant mode in the dual-mode resonant cavity is not the base film but the high-order mode, the length of the resonant cavity Compared with the width, the method of capacitance loading in the dual-mode cavity used in this article reduces the length and width by half, and the capacitor loading solves the problem of relatively close parasitic passbands in dual-mode technology. And using the resonant cavity zero position can be at the high end of the passband or at the low end of the passband, we designed a duplexer whose volume is 1/4 of the volume of an ordinary direct-coupled cavity duplexer.
