Cover Story: We present dielectric resonator-based microstrip filters (DRMFs) with innovative input–output coupling and tunable transmission/equalization zeros (4-2-0 and 4-0-2 configurations). Designed for space/radar applications, these filters achieve loaded QL > 3000 in the X-band—surpassing conventional microstrip filters (QL ≈ 200)—with S11 < −16.5 dB, flat S21, and >30 dB out-of-band rejection. Mechanical tuning enables precise control of coupling and frequency synthesis, while equalization zeros tailor group delay. DRMFs bridge the gap between dielectric cavity filters and microstrip technologies, offering a high-performance RF solution. View this paper
