Abstract
In general the embodiments described herein can provide alternating-current (AC) resonating filters. These resonating filters comprise a transmission line, a first resonator, and a second resonator. The first resonator is configured to block AC signals in a first frequency range, while the second resonator is configured to block AC signals in a second frequency range, where the second frequency range is higher than the first frequency range. The transmission line has a first node coupled to an AC source, and the first resonator is coupled to the transmission line a first distance from the first node, and the second resonator is coupled to the transmission line a second distance from the first node, where the second distance is greater than the first distance. When so configured the resonating filter can effectively block signals in multiple selected frequency bandwidths.
