The filter based on ring double mode resonator can improve the performance of filter selection and reduce the size of filter, so it is widely used in the design of filter parts. At the same time, with the development of integrated passive device integrated Passive device, it is possible to further miniaturize the filter. Therefore, in order to meet the higher requirements of various advanced microwave systems for device size, the miniaturization design technology of ring dual-mode resonator and its related filter parts based on IPD technology is studied in this paper.

The method of calculating the initial values of each lumped parameter element in the loop dual-mode band-pass filter circuit with lumped parameter structure is presented quantitatively, and the thin film IPD technique is used.

Based on the proposed topology of the full lumped element dual-mode resonator, a miniaturized C-band duplex based on lumped parameter dual-mode resonator is designed by using IPD technology. A series of parallel short circuit microstrip lines are used to construct the impedance matching structure. The overall area size of the duplex is 2.488mm 脳 2.668mm. 3. The effect of capacitive elements on the performance of dual-mode band-pass filters with lumped parameters is studied, and the variation of the central frequency and bandwidth of the filters with the capacitive components is given. A three-dimensional hybrid tunable band-pass filter based on lumped parameter dual-mode resonator is designed for miniaturized UHF band. The core size of the filter is 14.42mm 脳 9.306mm 脳 2.394mm.
