摘要： 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.

摘要： An RF circuit includes a first dielectric material, a signal line and a bias line over a first surface of the first dielectric material, a conductive layer over a second surface of the first dielectric material, and a second dielectric material over the conductive layer. The first and second dielectric materials have different dielectric constants. The conductive layer includes a ground plane over which the signal line is formed. A conductive material void, with which a section of the bias line is aligned, is present in the second conductive layer. The RF circuit further includes a mounting area for an RF device. First ends of the signal line and the section of the bias line are located proximate to the mounting area to enable the signal line and the bias line to be electrically coupled with one or more leads of the RF device.
