Abstract
Dielectric resonator bandpass filters with various time-delay at 800MHz were designed and fabricated in this paper. from the results of this study. first of all, good response. characteristics were measured for all cases. The insertion loss was below 2dB and flatness for ripple was below 0.2dB, whereas return loss was over 20dB, respectively. The measured delay time of the fabricated prototype were 6ns, 12ns and 200s, respectively and the flatness characteristics did not exceeding Ins for all cases. Furthermore, 2~4ns of flatness were measured for 2-hole dielectric block and other dielectric resonator filters with various delay time by combination of each prototypes filters were also implemented.
