A new ultra-wideband monocycle pulse generator with good performance is designed and demonstrated. The pulse generator circuits employ SRD(step recovery diode), Schottky diode, and simple RC coupling and decoupling circuit, and are completely fabricated on the planar microstrip structure, which have the characteristic of low cost and small size. Through SRD(More)
An improved ultra-wideband (UWB) microstrip filter with good out-of-band performance is designed and demonstrated. The filter is designed with two multiple-mode resonators (MMR), which are coupled together via a parallel-coupled line. A novel rectangular slit compact microstrip resonant cell (CMRC) is applied to improve the filter performance, which is(More)
