报告摘要：In recent years, the rapid development of modern wireless communication technologies has imposed more severe requirements on the RF/microwave components and circuits. Highperformance dielectric resonator (DR) bandpass filters (BPFs) have become essential components in many RF/microwave systems and have been receiving continuous attentions due to their many distinctive advantages like low loss, small size, light weight, and temperaturestable property. In particular, multi-mode DRs are preferred because they can further reduce both the size and weight of BPFs. However, due to the complicated field distributions in multi-mode

DRs, accurate design of BPFs using multi-mode DRs is still a challenging work.

This lecture reviews our recent works on the accurate design of high-performance BPFs using multi-mode DRs for future applications in wireless communication base stations. It includes three parts. In Part I, a precise design method of high-order BPFs with complicated coupling topologies is developed, and an example design of an 11-pole TM010 DR BPF is provided. In Part II, novel combined coaxial and dual-mode DR BPFs are precisely designed with fully controllable TZs, and symmetrical or asymmetrical filter responses are realized with excellent satisfactions of design specifications. In Part III, a novel compact high-performance 11-pole BPF is developed by using two triple-mode DRs and five coaxial TEM-mode resonators. The designed 11-pole DR BPF provides the advantages of reduced size and weight, low-profile, high frequency selectivity, fully controllable bandwidth and TZs, and excellent spurious performance. All the designs of the multi-mode DR BPFs meet the design specifications quite well, and are approved well by measured responses which agree excellently with their theoretical predictions.
